Suspended from an insulating thread and hangs among plates

Reference no: EM13678876

A small plastic ball of mass 9.34×10^-3 kg and charge +0.144C are suspended from an insulating thread and hangs among the plates of a capacitor (see the drawing). The ball is in equilibrium, with the thread making an angle of 30.0^o with respect to the vertical. The area of each plate is 0.01517 m². What is the magnitude of the charge on each plate?
