I wanted to hear the symmetry argument thank you very much
Aayush Sethia
May 29, 2024 17:03
The proof that I have attached with the post ?

Sir at last please tell me the problem with the gaussian surface proof ?
Aayush Sethia
May 29, 2024 17:03
Ok sir and what is the problem with the gaussian surface proof ?
Aayush Sethia
May 29, 2024 17:03
Sir then if it is non conducting then can I say that the field inside is 0 ?
Aayush Sethia
May 29, 2024 17:03
byjus.com/question-answer/… are they wrong here ?

where sigma is charge density

So tell me sir if I have shell and I want to find field at centre then is it not sigma / 4epsilon not ?
Aayush Sethia
May 29, 2024 17:03
Sir may I know why I cannot make both assumptions together ?
Aayush Sethia

Sir please see the latest edit as well

Sir , I actually want to draw an analogy between and a metallic solid hemisphere and a holow metallic hemisphere , as both are conducting so could I say that as inside a solid metallic hemisphere the field is zero then inside a hollow one also the filed should be zero ?
Aayush Sethia
May 29, 2024 17:03
Sir, I assuming uniform charge distibution at the surface of the hemisphere

it is conducting , yup it is sigma over epilson not for field

Would be highly helpful if you could help me solve this question with elastic collision condition , I know the Youngs modulus , area of cross section of the string as well .
Aayush Sethia
Mar 21, 2024 01:13
So is the question actually wrong as they say , that the string is inextensible and you say that the string compulsorily needs to get stretched due to the inelastic collision ?

I successfully found velocity
Aayush Sethia
Feb 4, 2024 07:09
Please help only in the acceleration part
Aayush Sethia
Feb 4, 2024 07:09
See I have taken velocity with respect to point O and it coming out to be 2wr
Aayush Sethia
Feb 4, 2024 07:08
Exactly
Aayush Sethia
Feb 4, 2024 07:08
In the question I am not able to understand why in the acceleration part we cannot do (2wr)^2 /2r

This means " If in the question it is not written about any type of friction I assume that the force is conservative and it does not dissipated energy "
Aayush Sethia
Dec 31, 2023 07:06
dissipates
Aayush Sethia
Dec 31, 2023 07:06
?
Aayush Sethia
Dec 31, 2023 07:06
Only friction dissipated energy
Aayush Sethia

How do I know if a force is conservative just by looking at its formula

A particle of mass m is initially at rest at the origin. It is subjected to a force and starts moving along the x- axis. Its kinetic energy K changes with time as dK/dt = t, where  is a positive constant of appropriate dimensions. Which of the following statements is (are) true?
(A) The force applied on the particle is constant
(B) The speed of the particle is proportional to time
(C) The distance of the particle from the origin increases linearly with time (D) The force is conservative

I think at point B and A the vel. should be same so how can Bernoulli be applied ?
Aayush Sethia
Dec 29, 2023 06:31
For this question I have seen people applying Bernoulli equation at point B but although isn't point B inside the tube

I hope you can find the picture online

A horizontally oriented tube AB of length l rotates with a constant angular velocity ω about a stationary vertical axis OO’ passing through the end A (Fig. 1.86). The tube is filled with an ideal fluid. The end A of the tube is open, the closed end B has a very small orifice. Find the velocity of the fluid relative to the tube as a function of the column height h.
