Which of the following changes would double the force between two charged particles? A. Doubling the amount of charge on each particle
B. Increasing the distance between the particles by a factor of 2
C. Decreasing the distance between the particles by a factor of 2
D. Doubling the amount of charge on one of the particles

Doubling the amount of charge on one of the particles.

Explanation:

The force between two charges is given by :

Where

r is the distance between charges

or

On doubling the charge on one of the particle,

F' = 2F

So, the force gets doubled. Hence, the correct option is (d).

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
