Problem 22.51 A slab of insulating material has thickness 2d and is oriented so that its faces are parallel to the yz- plane and given by the planes crd and = -d. The y- and 2-dimensions of the slab are very large compared to d, so treat them as infinite. The slab has charge density given by p(x) = po (c/d)', where po is a positive constant. Part A Using Gauss's law, find the magnitude of the electric field due to the slab at the center of the slab 2 = 0). Express your answer in terms of some or all of the variables po, d, 3 and electric constant Eo. IV ALQ R O O ? Ex=0 = Submit Request Answer Part B Identify direction of the electric field due to the slab in different areas. Drag the labels to their appropriate locations in the diagram. Labels can be used once, more than once, or not at all. O va 0 d
