A slab of insulating material has a nonuniform volume charge density
given by rho = Cx2, where C is a positive constant and x is measured from the slabs center. The slab is infi nite in the y and z directions.
(a) Find the electric fi eld for |x| > d=2, that is, in the regions exterior to the slab.
(b) Find the electric field for |x| < d=2, that is, in the interior region of the slab.
The Attempt at a Solution
I tried thinking in terms of gauss' law but i'm term how to tackle this problem
