One of the common uses for a coaxial cable is to transmit radio frequencies. One such coaxial cable of length 47.0 m consists of an inner conducting cylinder with a radius of 1.15 mm and an outer conducting cylinder whose inner radius is 3.25 mm. The charges on the inner and outer cylinders are −7.90 µC and +7.90 µC, respectively. (a) Determine the potential difference between the two cylinders along a path from the inner cylinder to the inside edge of the outer cylinder. Use the fact that the magnitude of the electric field at a distance r from the axis of the inner cylinder is given by  E = 2kλ/r    where k is Coulomb's constant and λ is the linear charge density.   (b) If the space between the two cylinders is filled with air, determine the capacitance of the cable.
