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? :)

• PHYSICS -

Use Coulombs law

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

• PHYSICS -

I used the formula, but I still don't know how to solve the problem ? Did you get it ?

• PHYSICS -

Did anyone get the answer for this?

• PHYSICS -

You have to convert km to m
