Two small similar balls of mass m are hung by silk threads of length l from the same point , a small angle apart and carry similar charges q. They lose charge and draw closer quasistatically .Calculate the rate of loss of charge if the relative velocity varies as `v=k/sqrtx`where k is a constant.

Text Solution

Verified by Experts

The correct Answer is:
