How does increasing the distance between charged objects affect the electric force between them?

a
The electric force increases because the distance has an indirect relationship to the force.
b
The electric force decreases because the distance has an indirect relationship to the force.
c
The electric force increases because the distance has a direct relationship to the force.
d
The electric force decreases because the distance has a direct relationship to the force.

b. The electric force decreases because the distance has an indirect relationship to the force.
