4. An infinitely long nonconducting solid cylinder of radius a has a nonuniform volume charge
density. This density varies with r, the perpendicular distance from its axis, according to p = br²,
where b is a constant. (a) Show that the linear charge density of the cylinder is given by λ = πba¹/2.
Find the expression for the electric field for r <a.
Hint: Compute for the total charge contained inside a cylinder of length L by considering multiple
shells of the cylinder. Afterward, use the relation Q = AL to identify the linear charge density.
