1. Two identical, small insulating balls are suspended by separate 0.25 m threads that are attached to a common point on the ceiling. Each ball has a mass of 2 x 10-3 kg. Initially the balls are uncharged and hang straightdown. They are then given identical positive charges and, as a result, spread apart with an angle 36° between the threads. Determine a) the charge on each ball and b) the tension in the threads. 360 L= 0.25 m
