Answer: A long, nonconducting, solid cylinder of radius
Chapter , Problem 32(choose chapter or problem)
A long, nonconducting, solid cylinder of radius 4.0 cm has a nonuniform volume charge density p that is a function of radial distance r from the cylinder axis: p = Ar2. For A = 2.5 /hC/ms, what is the magnitude of the electric field at (a) r = 3.0 cm and (b) r = 5.0 cm?
