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?

Answer 1

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

Answer 2

u spelled physics wrong
