The cross section of a long coaxial cable is shown in the figure, with radii as given. The linear charge density on the inner conductor is -20 nC/m and the linear charge density on the outer conductor is -90 nC/m. The inner and outer cylindrical surfaces are respectively denoted by A, B, C, and D, as shown.
