A small plastic ball of mass 5.55 x 10-3 kg and charge+0.192C is suspended from an insulating thread and hangs betweenthe plates of a capacitor (see the drawing). The ball is inequilibrium, with the thread making an angle of 30.0owith respect to the vertical. The area of each plate is 0.02015m2. What is the magnitude of the charge on each plate?
