(22-46) A flat slab of nonconducting material (Fig. 22-40) carries a uniform charge per unit volume

(22-46) A flat slab of nonconducting material (Fig. 22-40) carries a uniform charge per unit volume, ρ_E. The slab has thickness d which is small compared to the height and breadth of the slab.Determine the electric field as a function of x (a) inside the slab and (b) outside the slab (at distances much less than the slab’s height or breadth).Take the origin at the center of the slab.
