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 -26.8 nC/m and the linear charge density on the outer conductor is -60.0 nC/m. The inner and outer cylindrical surfaces are respectively denoted by A, B, C, and D, as shown. Find the radial component of the electric field at a point that 37.3 mm from the axis to the nearest N/C.
