A charge Q is carried from A point a (r,135°) to point B(r,45°) following a path which is a quadrant of circle of radius r. If the dipole moment is P then find out the work done by external agent

Dear student,

The question is not very clear. What dipole moment is being talked about? Here we were talking about a single charge being carried from one point on the circle to the other. Please clairfy the question so that we could help you with the solution.

Regards.
