Suppose you have two point charges,+Q and -q.As you pull them farther and farther apart,you increase the potential energy of this system relative to infinity.

Question

Quizplus · Accepted Answer

As the two point charges are pulled farther apart, the potential energy of the system increases relative to infinity, which means work has to be done against the electrostatic force between them to move them apart. Therefore, it is true that the potential energy of the system increases as the charges are separated.
