Assuming that's not rhetorical... You can’t. But there’s a possibility that a 60° angle was accidentally omitted from the question -...

1.15mm is a bit thin to call a rope! A ‘cord’ might be a better term. Nylon is stretchy, but this won’t affect the answer to the...

That’s one way of thinking about it. But I’m not convinced that is the intended interpretation. The ionisation energy of a molybdenum...

This is (IMO) a badly written question for another reason. The final state of the atom is ambiguous. Is it: a) missing only an...

Here’s a strategy to find the final state: 1) Calculate the amount of energy (A) needed to warm the ice to 0 deg.C. 2) Calculate the...

This post makes everything clear. Very high quality. All my doubts on this question got cleared! for a) I will take the direction of...

@palaphys, for an intuition, it helps to visualise flux lines. In the following diagram, the magnitude of the flux through the loop due...

1.##\frac{q}{\epsilon_0}## 2. ##\frac{-q}{\epsilon_0}## 3a)0 b)0

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...
