Consider the electric force between a pair of charged particles a certain distance apart. by coulomb's law: if instead, the distance between the particles is doubled, the force becomes

a. one fourth.
b. half.
c. double.
d. 4 times.

Explanation:

The electric force between two charged particle is given by :

d is the distance between charged particles

Let F' is the force when the distance between the particles is doubled, d' = 2d

New force is given by :

The new force becomes one fourth of the original force. So, if the distance between the particles is doubled, the force becomes one fourth.

option number c is the right answer.
