Two identical plane metallic surfaces A and B are kept parallel to each other in air separated by a distance of 1.0 cm as shown in the figure. Surface A is given a positive potential of 10V and the outer surface of B is earthed.
(a) What is the magnitude and direction of uniform electric field between point Y and Z? What is the work done in moving a change of 20 µc from point X to Y?
(b) Can we have non-zero electric potential in the space, where electric field strength is zero?
