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?

Question

I'm confused, help pleeease? :)

Answer 1

Use Coulombs law

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

Answer 2

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

Answer 3

Did anyone get the answer for this?

Answer 4

You have to convert km to m
