Problem: For a positive charge moving in the direction of the electric field,a) its potential energy increases and its electric potential decreases.b) its potential energy decreases and its electric potential decreases.c) its potential energy decreases and its electric potential increases.d) its potential energy and its electric potential both remain constant.e) its potential energy increases and its electric potential increases.

FREE Expert Solution

The electric field points in the direction of decreasing electric potential. Hence, the positive charge is moving in the direction of decreasing potential.

The potential energy of a positive charge increases when it moves against the electric field and decreases when it moves in the direction of the electric field.
