Question 9 • *KCPS Physics First (2027)

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

Answer
A
The electric force decreases because the distance has an indirect relationship to the force.
B
The electric force decreases because the distance has a direct relationship to the force.
C
The electric force increases because the distance has an indirect relationship to the force.
D
The electric force increases because the distance has a direct relationship to the force.

Explanation

Coulomb’s law says the electric force is inversely proportional to the square of the distance between charged objects: as distance increases, force decreases. For example, doubling the distance makes the force one-fourth as strong. This is an indirect relationship, so the correct choice is A, “The electric force decreases because the distance has an indirect relationship to the force.”
