By ThaMNDIasA #2 A Uniformly Charged Slab 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 x - d and x - -d. The y- and z-dimensions of the slab are very large compared to d and may T be treated as essentially infinite. The slab has a uniform negative -d d. charge density P. miogb (a. ) Explain why the electric field due to the slab is zero at the center of the slab (r = 0). (b.) What is the direction of the electric field at any point r > 0. Explain. (c. ) Using Gauss's law derive an expression for the magnitude of the electric field inside the slab for all points 0 d in terms of the charge density p. (e.) Explain why no new derivations are needed in order to find the magnitude and direction of the electric field at all points to the left of zero (-d
