Two identical point charges are separated by a distance of 3.0 cm and they repel each other with a force of 4 X 10^-5 N. What is the new force if the distance between the point charges is doubled?

An inverse square law applies tp both gravitational and electrostatic forces.

If you double the distance between two objects, the force is decreased by a factor of 1/2^2, which is 1/4

Multiply that by the original force and you get 1 x 10^-5 N
