IP A point charge of mass 9.9×10⁻² kg and charge +6.77 δC
is suspended by a thread between the vertical parallel
plates of a parallel-plate capacitor, as shown in the figure
(Figure 1).
Part 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?
The right plate
The left plate
Part 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?
