A point charge of mass 0.081 kg and charge +6.77 μC is suspended by a thread between the vertical parallel plates of a parallel-plate capacitor, as shown in Figure 20-30. (a) If the charge deflects to the right of vertical, as indicated in the figure, which of the two plates is at the higher electric potential? (b) If the angle of deflection is 22°, and the separation between the plates is 0.025 m, what is the potential difference between the plates?
