Reference no: EM132762320

A small plastic ball of mass 7.86 × 10-3o2 kg and charge +0.178C 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 30.0 with respect to the vertical. The area of each plate is 0.01246 m. What is the magnitude of the charge on each plate?
