The cross section of a long coaxial cable is shown in the figure, with radii as given. The lincar charge density on the inner conductor is -40 nC/m and the lincar charge density on the outer conductor is -50 nC/m. The inner and outer cylindrical surfaces are respectively denoted by A, B, C, and D, as shown.
