Question
A positive charge is initially at rest and then allowed
to move freely in a region where there is a uniform electric field. What happens to its electric potential energy as it begins to move?Solution
When a positive charge is released from rest in a uniform electric field , it experiences a constant force in the direction of the field and begins to accelerate. As it moves, it loses electric potential energy because it is moving from a region of higher electric potential to lower electric potential . This decrease in potential energy is converted into kinetic energy, in accordance with energy conservation.
