Two identical thin rings, each of the radius R are coaxially placed at a distance R from each other. If `Q_(1) and Q_(2)` are the charges uniformly distributed on the rings, then calculate the work done in moving a charge q from the centre of one ring to the centre of the other.

Text Solution

Verified by Experts

The correct Answer is:
`q/(sqrt(2)R)(Q_(1)-Q_(2))(sqrt(2)-1)`
