Two Squares plates have the surface charge densities of +0 and o and sides of length L. They are face to face next to each at a distance of 0.01 L apart. Let kc = 1 . ll 0.01L a. What is the magnitude of the electric field in the middle between the centers of both plates? b. What is the magnitude of the electric field in the middle between the centers of both plates in the near-field approximation? 0. What is the relative error of the near-field approximation
