Two small balls, each of mass m = 3.1 g, are attached to silk threads of length = 50 cm, which are in turn tied to the same point on the L ceiling, as shown above. When the balls are given the same charge Q, the threads hang at 0 = 4.7 to the vertical. a) Each of the charges Q is subject to how many forces in this case? The number of forces experienced by Qis: 3 b) What is the magnitude of the gravitational force acting on Q? F 30 N X c) What is the magnitude of the net force acting on Q? |Fnet = d) What is the magnitude of the electrical force acting on Q? E e) What is the magnitude of Q? |Q|= f) How do the signs of the two charges compare?
