Electric Forces - E and V Charged Plates

Question 1

notes

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). When you lift up an object, you are increasing its gravitational potential energy. Likewise, as you are lowering an object, its gravitational energy is decreasing.
