@JMac what do you think about my handwriting? :P

@JohnRennie my notes^

Does anyone explain e.g. : why charge q1 apply same 10N force on q2 when 2 charge system.

and in 3 charges system why q1 apply same electrostatic force on 10N on q2 and 10N on q3.

same for n number of charges.

I asked this question because this chatroom has experienced physicist and found satisfactory answers here.

what does the number of charges have to do with anything?

Coulomb's law doesn't care what other charges there are, it just tells you the force between two charges

@ACuriousMind Yes you are right. but is it possible for us to explain this phenomenon intuitively.

I'm not sure what sort of explanation you're looking for. Forces are always between two objects. If I push you, it doesn't matter whether other people are pushing you or not, it doesn't change the force I'm exerting at all.

Let say q1 = 10N. In two charges q1 apply 10N on q2. In more charges the same 10N it apply on every single charge. From where q1 has more 10N force for other charges if it utilize in q2.

Things don't "have force" (and charge is not measured in Newton)

If you're asking where the energy for the work being done comes from, it's in the electromagnetic field - someone must have done work to separate the charges (if they're oppositely charged) or to bring them this close together (if they're of the same charge)

@ACuriousMind Yes i asked question about force. If a person has only 10N force. It apply on a box. It does not have more force to apply on other box on the floor. The analogy use for charge.

The force between charges is more like that exerted by a spring than that of a person. Imagine a bunch of particles where each is connected to the others via a spring. You wouldn't be wondering why moving one particle exerts forces on all the others, would you?

and now I see that John has already talked to you about this

Couldn't you have been more precise and explained what you didn't understand about his explanation rather than just act as if you asked the question here for the first time?

Yo!

Yo?

@M.N.Raia I don't know, I think quotes like "Today I want to tell you how particle physicists are wasting your money" and "Frankly, the way that particle physicists behave makes me feel embarrassed I ever had anything to do with their field." as part of a big tirade against particle colliders with red-herrings about supersymmetry thrown in for fun isn't exactly a pro-science position

@FakeMod are you actually going to say something else this time or is this another round of "hey"? :P

Dear i don't understand. In two charges system. If q1 has 10N force it attract/repel q2 by the same amount and it consuming in attract/repel to q2. And i add q3 in a plane (analogy of mass-spring system). It should not attract/repel q3. If it is a mass-spring system between all 3 charges. q1 10N must distribute between q2 and q3. But in Coulomb's law we use q1 = 10N for q2 and q3. why

@ACuriousMind I was just reading that John Rennie conversation and I saw a "Hey!" "Hey?" after just reading your Yo's. That was a pretty good laugh.

@123 It doesn't consume anything. If you have two thing connected by springs, and you add another one in, it will take energy or increase energy to add that third to the system, but it doesn't reduce how much spring force is between each pair of charges.

@ACuriousMind Less is my time, waste it I cannot.

That's some shitty yoda-talk.

Anyways, how's life?

You can't waste time, so coming it and saying "Hey!" then leaving is productive? :P

Mine is significantly more free and enjoyable.

@JMac How it increase energy? Where it comes from?

@bolbteppa, I completely agree, I am no reasercher so my opinion can't be based on concrete facts, but just the way the opinion it was exposed wasn't very scientific

@JMac No, that was just probably once (or thrice). I am ready and free to talk now. Moreover, dropping by at least gives me a sense of a belongingness which I don't think I want to let go.

LaTeX is so cruel :(

@123 From the work the person putting in the spring is doing while they do that

@123 It comes from however you added the new charge to the system. Or, as was said:

Why can't it be more user-friendly?

Am I the only person who thinks that I am chat-bombing a productive conversation?

Meh it's not that cluttered right now IMO

@FakeMod It's not intended to be user-friendly, it was written by a programmer with weird ideas about what makes "readable" code and designed to produce passable output on machines closer to potatoes than modern computers in their processing power

E.g. all the weird "you have to compile it X+1 times for an everchanging value of X" stuff is because it drops all sorts of information into files since it ran on machines that couldn't hold all the information in memory

@JMac Hmmm... I see let me think this idea. By the thanks for contribution.

the often cryptic error messages are probably another consequence of this - proper error recovery takes effort and memory that were not always available

@ACuriousMind If Tex.SE wouldn't have existed, then I guess all noob LaTeX users (like me) would have either died trying to remove the errors, or would've given up on LaTeX.

@FakeMod back in the days you had to read the manual and you had to like it!

I think in electrostatic there is no magnetic field. I think you meant electric field? Am i right or wrong.

@ACuriousMind Yup. I don't even understand the error messages, man. They reprimand me for doing stuff that I didn't even do. Nobody does that.

I can't think to solve latex errors with a manual, even though probably helps you more to understand it really

@123 "The electromagnetic field" is a catch-all term for both the electric and the magnetic field. They're not really distinct entities as you'll learn when you get to special relativity.

@FakeMod To programmers used to fighting with all sorts of strange compilation errors TeX doesn't seem all that terrible :P

@ACuriousMind @Ratman Manuals are great as long as you aren't getting any errors and doing stuff which is covered in the manuals. That's how I learned TikZ. But when you're getting errors or doing some stuff not documented in the manuals (usually the case when I am doing LaTeX), it feels damn hard to get ahead using just manuals.

@ACuriousMind To them. (BTW what are we drinking?)

What i am thinking may be it is natural phenomenon what we know just by experimentation. By adding charges to system the same force exert on each charge in the system. That's why none of the book/writer explain this phenomenon why it happened.

May be i am wrong.

@123 All physics is just natural phenomena that we've observed and fitted into neat little mathematical models.

@ACuriousMind I bet this is not the first time this chatroom has seen this comment.

I'm sure I've said similar things over the years, yes

Tikz is used for drawing feynman diagrams?

@ACuriousMind i asked this question. May be humans found the answer to this question.

I mentioned this yesterday, but I've been playing more of it and I really gotta say anyone who enjoys kinda surreal puzzle games should check out Manifold Garden store.steampowered.com/app/473950/Manifold_Garden It's such a cool idea; not only do you change the surface gravity acts on, but the levels repeat in infinite patterns so you can do really cool things and it gives a really cool atmosphere.

@FakeMod :) yo..

@Ratman There's a special package for drawing Feynman diagrams, AFAIK (which of course uses TikZ under the hood).

Once again i don't know the meaning of yo in this chatroom.

it's just yo

@123 yo

Means Yo replacement of hello with happiness.

You don't question the "yo", young padawan.

can't remeber how I drew them, even though it was quite painful

@JMac I'm happy for other people that puzzle games exist but they usually either just bore or frustrate me regardless of how atmospheric they are :P

@FakeMod Oh i see. I google it padawan. It is learner inexperience and biggenner

@ACuriousMind I have a few specific types of puzzle games that I usually flock to. Like I played Portal 1 and 2, those were just fun. Besides that it's usually just games with weird mechanics. I've played some pretty cool ones, but the last one I beat was probably Antichamber like 4 years ago.

Okay, even I loved Portal 2 Co-Op, I'll give you that

@JMac have you played Monument Valley?

Also everyone saying "Yo!" all I can think of is the Dean in Discworld, even though I do say Yo often enough

@JohnRennie I've seen that before but I haven't played phone games in so long I never played it.

@JMac it's not especially hard, but I found it quite charming. I've been playing it on my Chromebook rather than on a phone.

Why we create idea of work done. What is benefit of creating this idea.

@123 we define energy with it.

What is the benefit of defining energy beside other quantities e.g1; Force etc/

@123 it is conserved and makes calculations simpler. Also it makes the task of thinking things intuitively much easier.

@123 See physics.stackexchange.com/q/138972/50583, physics.stackexchange.com/q/3014/50583

Because electrostatic/gravity follow inverse square law. And potential 1/r law for same system.

worked one hour just to reduce the computing time of two seconds, not a great result

Considering how inefficient It was before

Yeehaw!

@FakeMod Hi

Hi

@knzhou That is super helpful, my email is [email protected] . If you send me an email I can gladly send you the thesis

@EmilioPisanty I politely decline this offer; it’ll happen on its own soon enough, and I would prefer it that way.
