When two like charges are brought together, the potential energy of the system formed will
A
increase because work is done against the field
B
increase because work is done by the field
C
decrease because work is done by the field
D
decrease because work is done against the field
Verified Correct Answer: A.
Physical Principles & Numerical Solution
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.
