Homework Help: PHYSICS

A thundercloud has an electric charge of 43.2 C near the top of the cloud and -38.7 C near the bottom of the cloud. The magnitude of the electric force between these two charges is 3.95 x 106 N. What is the average separation between these charges?

I'm confused, help pleeease? :)

Use Coulombs law

force=kQtop*Qbottom/d^2 solve for d
