Two identical, small insulating balls are suspended by separate 0.31-m threads that are attached to a common point on the ceiling. Each ball has a mass of 7.2 x 10-4 kg. Initially the balls are uncharged and hang straight down. They are then given identical positive charges and, as a result, spread apart with an angle of 38° between the threads. Determine (a) the charge on each ball and (b) the tension in the threads.
