A system of two charges separated by a certain distance apart stores electrical potential energy. If the distance between them is increased, the potential energy of the system,

A

may increase or decrease

B

increases in any case

C

remains the same

D

decreases in any case

Text Solution

Verified by Experts

The correct Answer is:
A
The potential energy of the system, U is proportional to product of the charge and inversely proportional to the distance. As the distance increases, potential energy can increase provided the charges are of the same polarity. If unlike polarity, the potential energy will decrease.
