Question

A positive charge is moved from a low potential to a higher potential point . The change in its electric potential energy is

Answer 1

If a charge is moving in the direction that it would normally move, its electric potential energy is decreasing. If a charge is moved in a direction opposite to that of it would normally move, its electric potential energy is increasing. This situation is similar to that of constant gravitational field (g = 9,8 m/s2).
