A small plastic ball with a mass of 6.50 × 10-3 kg and with a charge of +0.150 µC is suspended from an insulating thread and hangs between the plates of a capacitor (see the drawing). The ball is in equilibrium, with the thread making an angle of 30.08 with respect to the vertical. The area of each plate is 0.0150 m2. What is the magnitude of the charge on each plate?
