Two identical nickel balls are 2 meters apart from each other. The volume of the balls is 1 cm3. Suppose someone can move one electron from each atom of ball A and give it to ball B.
What is the magnitude of the electrostatic force between two nickel balls?

what is the magnitude of the gravitional force between two nickel balls?

(in units of N)

How many electrons would need to be transferred in order to balance these two forces?
