The derivation of lens maker's formula already encapsulates the condition of refractive index of medium being different from that of the...

I'm not sure where you got this formula from. I've referred to more than 1 book, but couldn't find your version of the formula. I've...

I don't understand how did you reach that conclusion. Study material is NOT provided by NTA. As far as I know, only syllabus is provided...

Yes, you’re right. I had (badly) misunderstood the nature of unacademy. It is not linked to NTA. It appears to be a (fairly large...

In that case I agree with your values for the magnitudes of the fluxes. Though I would write '2/10' as '1/5'! Imagine lines of flux as...

Hi. A few thoughts… You haven’t given the radius of the ring. You haven’t mentioned how you have dealt with the charge of 2q on the...

As I understand it, NEET (UG) is an entrance examination set by the Indian National Testing Agency (NTA) for entrance to medical...

Thank you all the same for I got my answer from the general formula you provided.

I’m not entirely sure why optical power is defined as ##P_m = \frac {\mu_m}{f_m}##. I suspect that the main reason is to enable powers...

Welcome to PF @shubhamakshit. The above formula only applies to a thin lens when the surrounding medium is air/vacuum (refractive index...

[Water] siphons stop working at about 0 C.

@Zayan, a few thoughts... This looks a relatively advanced problem – halfway between a simple pendulum and a double pendulum. It would...

I don’t understand the question. Referring to Post #5, Q1, the current around loop ABCD is the eddy current in this situation. (If...

Yes, you got it. The same thinking can be applied to the Figure 2 diagram from your link. The exact shape of the loop and the exact...

So in 1. is it anticlockwise cuz current induced between points C and B go from C to B and for 2. it is clockwise
