Question

Two identical charged rings of charge Q = 1 and radius R = 0.1m are separated by a distance $\sqrt{3} R$ meter, and are fixed. A point charge of charge $q = 1.0 \times 10^{- 9} C$ and mass m = 2 kg is moved by external agent from the centre of left ring to the centre of right ring. Find the work done by an external agent in ___ joule.

Solution

The potential at the centres of Left and Right rings are equal and work done = $Δ U = q Δ V = 0$
