Question

A long, conductive cylinder of radius R1 = 3.40 cm and uniform charge per unit length λ = 453 pC/m is coaxial with a long, cylindrical, non-conducting shell of inner and outer radii R2 = 11.9 cm and R3 = 13.6 cm, respectively. If the cylindrical shell carries a uniform charge density of ρ = 40.5 pC/m3, find the magnitude of the electric field at the following radial distances from the central axis:

R1 = 2.58 cm

R2 = 7.65 cm

R3 = 12.2 cm

R4 = 18 cm
