Question
A nonconducting ring of radius R has two charges q and q/2 distributed uniformly on two half of it. A negative charge q/2 (mass = m) is placed at a distance R from the centre of the ring on its axis at a point P and released. If this charge is restricted to move freely only along the axis of the ring, find the speed of this charge when it crosses the centre of the ring
The correct answer is:
