A Uniformly Charged Slab. A slab of insulating material has thickness 2 d 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 ; treat (hem as essentially infinite. The slab has a uniform positive charge density ρ . (a) 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 electric field due to the slab (magnitude and direction) at all points in space.
