Three 14.05-g Styrofoam balls of radius 2 cm are coated with carbon black to create them conducting and then are tied to 1.23-m-long threads and suspended freely from a common point. Every ball is given the same charge, q. At equilibrium, the balls form an equilateral triangle with sides of length 20.64 cm in the horizontal plane. Decide the absolute value of q
