Question

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

• A. Remains a constant because the electric field is uniform.
• B. Increases because 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 1

Answer: (C)

Decreases because the charge moves along the electric field.

Answer 2

: In a uniform electric field, when a positively charged particle is released from rest, it moves along the electric field, that is from higher potential to lower potential. Therefore electric potential energy of charge decrease.
