Aelectron is released from rest in a uniform electric field oriented from left to right. what happens to the electric potential energy of the proton-electric field system? a. increaseb. decreasec. remains the same

Explanation:

When electron is released in an electric field , it will move in the direction opposite to the direction of field. In this process , force is applied by the field and work is done by the field. So its electric potential energy will be decreased because , its energy is converted into kinetic energy of the electron .
