A positively charged particle is released from rest in a uniform electric field. The electric potential energy of the charge.

Options

A. remains a constant because the electric field a uniform
B. increases becauses the charge moves along the electric field
C. decreases because the charge moves along the electric field
D. decreases because the charge moves opposite to the electric field

Answer

C

Explanation

In a uniform electric field, when a positively charged particle is releases from rest, It moves along the electric field (i.e., from higher potential to lower potential). Therefore, electric potential energy of charge decreases. Choice (c ) is correct.
