A long, nonconducting, solid cylinder of radius Z cm has a nonuniform volume charge density ρ that is a function of the radial distance r from the axis of the cylinder, as given byρ = Ar2, with A= Y µC/m5.
a) What is the magnitude of the electric field at a radial distance of X cm from the axis of the cylinder?
b) What is the magnitude of the electric field at a radial distance of W cm from the axis of the cylinder?
