(III) A flat slab of nonconducting material has thickness 2d, which is small compared to its height and breadth. Define the x axis to be along the direction of the slab’s thickness with the origin at the center of the slab (Fig. 22–41). If the slab carries a volume charge density ρE (x) = −ρ0 in the region −d ≤ x < 0 and ρE(x) = +ρ0 in the region 0 < x ≤ +d, determine the electric field
