Help for physics problem

[Bonhomme]

Hi,

I need help for problem 14. I don’t understand how to compare the second equation to the first so that I can answer in terms of F.

Thank you.

You must have done the equation that relates force to charge and distance (Coulomb’s Law)?

If not, look it up. If you don’t understand how to apply it, let us know

It is a bit hard to read, but if you are saying that the force increases by 4, then that is the right answer!
