Question
What is the amount of work done in moving a point charge Q around a circular arc of radius ‘r’ at the centre of which another point charge ‘q’ is located?
Solution
The work done in moving a charge along any circular path is zero. So, to move a point charge Q around a circular arc of radius ‘r’ at the centre of which another point charge ‘q’ is located, no work has to be done.
