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?
