OBJECTIVES
1. Calculate electric force using Coulomb’s law.
2. Compare electric force with gravitational force.
3. Apply the superposition principle to find the resultant force on a charge and to find
the position at which the net force on a charge is zero.

PS4c:
The electric force is a universal force that exists between any two charged objects.
Opposite charges attract while like charges repel. The strength of the force is
proportional to the charges, and, as with gravitation, inversely proportional to the
square of the distance between them.
