(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Positive charge is distributed throughout a solid non-conducting cylinder of radius 'b ' and infinite length. The charge density increases with radius according to ρ = [itex]{ρ}_{o}[/itex]([itex]{r}{^2}/{b}{^2}[/itex]), where [itex]{ρ}_{o}[/itex] is a constant (evidently equal to the charge density at the surface of the cylinder).

Find the electric field intensity, E, as a function of radius, outside the cylinder.

2. Relevant equations

E = k[itex]{dq}/{r}^{2}[/itex]

3. The attempt at a solution

Not sure where to get started, actually. If we try to find the electric field intensity at a position outside the cylinder wouldn't it be dependent on how far out we're finding the electric field and not dependent on the radius?
