When two like charges are brought together, the potential energy of the system formed will
-
increase because work is done against the field
- increase because work is done by the field
- decrease because work is done by the field
- decrease because work is done against the field
The correct answer is: A
Explanation
if two like charges are close together, they repel each other. moving them closer together requires working against repulsive force which increases the potential energy of the system.
