MHT CET 2024 Physics question

If a unit positive charge is shifted from a region of low potential to a region of high potential, then the electric potential energy of the system

(A)increases.Correct
(B)decreases.
(C)does not change.
(D)is zero.

Answer: (A)

Solution

Potential energy of a charge at a point of potential is . For a unit positive charge , so and . Therefore the potential energy of the system increases (external work is done against
