Consider an infinite slab of thickness 2a and uniform volume charge density ρ. This is essentially an infinite plane with a non-negligible thickness. Since the planar symmetry involves:艹-2 reflection symmetry, as well as the translation symmetry along the and y direc- tions, we place the origin at a point on the midplane of the slab. In other words, the midplane corresponds to oo = 0 (i.e., the ry plane) and the surfaces of the slab are at a (a) Use...
