What is E(r), the radial component of the electric field between the rod and cylindrical shell as a function of the distance r from the axis of the cylindrical rod? Express your answer in terms of λ, r, and ϵ0, the permittivity of free space. View Available Hint(s) E(r) E r E(r) = nothing Part B What is σinner, the surface charge density (charge per unit area) on the inner surface of the conducting shell? View Available Hint(s) σinner σ i n n e r sigma_inner = nothing Part C What is σouter, the surface charge density on the outside of the conducting shell? (Recall from the problem statement that the conducting shell has a total charge per unit length given by −2λ.) View Available Hint(s) σouter σ o u t e r sigma_outer = nothing Part D What is the radial component of the electric field, E(r), outside the shell?
