As in the text example, consider two “infinite” grounded
conducting plates (0 V) at y = 0 and y = a (parallel to the x-z
plane), bounding a variable Voltage section of material at x = 0,
such that V(y) = (a - y) and 0 < y < a. a) What's the
electric field in the section of the material (find it and sketch
it) ? Can this material be a conductor in electrostatic
equilibrium? b) Find V(x,y,z) in the empty region between the
infinite plates by solving Laplace's eqn.
