Ok no problem I solved it so no worries

So I just solely focus on x direction only

@JohnRennie

I got it has got acceleration in y direction but it has been asked to find maximum acceleration and minimum applied on wedge in x direction specifically

But when I apply the same logic to friction question it's wrong and in solution it has assumed no acceleration in y direction

Then I differentiated it twice and a-x(double dot)=y double dot

x-X=h-y

Then I subtracted x-X/h-y = tan45

I solved it by using the constraint relation of acceleration by measuring distance to x till block of mass m and X till wedge the in y direction I took total height of were h and the height till block is kept y

Ok wail I'll send the link

Does it have to do something with friction

The surface was smooth

It essentially is the same question but had no friction

No I mean a question from the previous chapter not this one

How come in y acceleration is zero in this question while the previous one had no friction but it had assumed the acceleration in y direction

And they didn't use constraints to solve it

When I am applying the same concept here the solution says acceleration in y direction is zero

By assuming acceleration in X and in both y direction

It had no friction

I solved it using constraints

In a similar question in the previous chapter of my book this was the same type of question and

My doubt is not solving it but something else

Yes

Wait I'll send a clear link

g.co/about/k9jfpf

Ok I'll try

In here there is no option

How do I post a picture of a question

Can you help me understanding a question

Hi:)

@JohnRennie

You're goat

I got it thanks

Yes

In answer

Yes there are two solution that is 2f and 4f are values of d

yeah you're right

Yes

Ok

Wait then we don't get another reflection if the image itself is virtual

If I keep it between the pole and focus I get virtual image

Which is not allowed

Yes I do get another reflection if I keep it at centre of curvature

At the case where it does not gets reflected to another mirror

By only one image I think only one reflection

I think I should let image be formed at centre of curvature

Hi

Is there any modern physics book which is not just plug the numbers and get the answer( I have books like Arthur beiser and paul tipler but they just throw formulas and in example number that have to be plugged and get the answer)

Ok
