(a) Find the electric potential at a general point in space for a charge placed as in Figure 5.14 with the angle between the plates equal to 60°. Assume the intersection between the plates occurs at x = 0, y = 0, the upper plane coincides with the y axis, and the charge q is on the bisector (at 30° from the y axis), at a distance a from the intersection of the plates.
(b) Find the electric field intensity on the vertical plate.
