A long coaxial carries a uniform volume charge density p on the inner cylinder with radius a and a uniform surface charge density on the outer cylindrical shell. 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: (a) inside the inner cylinder s < a (b) between the cylinder a < s < b
