A long coaxial cable (Fig. 1.2) carries a uniform volume charge density rho, on the inner cylinder (radius a), and a uniform surface charge density on the outer cylindrical shell (radius b). This surface charge is negative and is of just the right magnitude that the cable as a whole is electrically neutral. Find the electric field in each of the three regions: (1) inside the inner cylinder (sb). plot |E| as a function of s.
