Two 5 g metal balls hang suspended, with the balls just touching when they hang from a common support. Each ball's center is initially 1 m below the support. The balls are then each given an identical amount of charge q, and each string makes an angle of 30 deg with the vertical as shown in Figure below. Find the magnitude of the charge q.
