Two equal positive charges are held in place at a fixed distance.If you put a third positive charge midway between these two charges,its electrical potential energy of the system (relative to infinity)is zero because the electrical forces on the third charge due to the two fixed charges just balance each other.

Question

Quizplus · Accepted Answer

The electrical potential energy of the system will not be zero because the third positive charge will experience a net electrical force due to the two fixed charges. This force will cause the third charge to move, and as it moves, its potential energy will change.
