Question

If each of the charges doubles, what happens to the force?

Answer 1

Hi friend :)

______________________________________

If you are talking about electric force:

F =$\frac{kq_{1}q_{2}}{r^{2} }$

now as you can see in the formula itself, force is directly proportional to the product of the magnitude of two charges ,

if you double both charges, force will become four times its initial value.
