A long, non conducting, solid cylinder of radius 3.7 cm has anonuniform volume charge density ρ = Ar2, a function of the radial distance r from the cylinder axis. A = 2.4 µC/m5.
(a) What is the magnitude of the electric field at a radial distance of 2.7 cm from the axis of the cylinder?
N/C
(b) What is the magnitude of the electric field at a radial distance of 4.7 cm from the axis of the cylinder?
N/C
