Point charge between intersecting conducting planes. Two conducting planes intersect at 30°, as in Figure 5.39. Both surfaces are at zero potential. A point charge q is placed between the two planes at point A, as shown.
(a) Draw the system of image charges and calculate the electric field intensity everywhere between the planes.
(b) Show by means of a drawing what happens if the charge is moved from the center plane toward the upper plane so that it is at a distance b from the upper plane and a distance c from the lower plane while the radial distance is maintained (point B).
(c) Show by means of a drawing what happens if the angle is not an integer divisor of 180°. Use an angle of 75° as an example.
