Two small balls with a mass of 2 g each are hanging on two separate strings 0.5  m (50 cm)  long attached to a common point. They are given an identical negative charge and spread apart to a distance 6 cm from each other.   Determine the charge on each ball by finding the forces in equilibrium and using Coulomb's law.
