Question

A positive charge +q is located at a point.What is the workdone if a unit positive charge is carried once around this charge along a circle of radius 'r' about this point.​

Answer 1

Answer:

What is work done if a unit positive charge is carried once round this charge along a circle of radius r about this point? The potential on every point at a distance of r from the centre is same. Hence the work done is zero.
