Two small plastic spheres are given positive electrical charges. When they are a distance of 16.0cm apart, the force among them has a magnitude of 0 235N.
1) What is the charge on the second sphere?
2) What is the charge on each sphere if the two charges are equal?
3) What is the charge on first sphere if it has four times the charge of the other?
