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?

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90
