1.	A charge `+Q` is lying at the center of a circle. What is work done in carrying charge q from A to B, where A and B, both lie on the circle.
Answer» The circular path around the charge `+Q` is an eqipotential surface. As A and B lie on the circle i.e, on the equipotential surface, work done = 0.
