A coaxial cable is an electrical cable that has an inner conductor surrounded by an insulating layer, and then surrounded again by a conducting shield. Consider an infinitely long cable illustrated below that carries a charge of ₁ = 5 nC/m on its inner conductor, while the outer conducting shield in uncharged. a.) Find the charge density on the inside and outside surface of the conducting shield. b.) Find an expression for the electric field for all r. 5 cm CH 4 cm
