A slab of insulating material has thickness 2d and is oriented so that its faces are parallel to the z-plane and given by the planes x=d and x= - d. The y- and z-dimensions of the slab are very large compared to d and may be treated as essentially infinite. The slab has a uniform positive charge density \rhoa) Explain why the electric field due to the slab is zero at the center of the slab (x=0).b) Using Gauss's law, find the magnitude of the electric field due to the slab at the points 0<=x<=d. c) What is the direction of the electric field due to the slab at the points 0<=x<=d ?d) Using Gauss's law, find the magnitude of the electric field due to the slab at the points x>=d . Express your answer in terms of the variables \rho, x, d, and epsilon_0.e) What is the direction of the electric field due to the slab at the points x>=d?
