The figure below shows a long conducting coaxial cable and gives its radii (R₁ = 3.9cm, R₂-8.6cm, R3-17.1cm). The inner cable has a uniform current density of J = 7.2 A/m², and the outer cable carries a uniform current | = 4.3A flowing in opposite direction. Assume that the currents in each wire is uniformly distributed over its cross section. Determine the magnitude of the magnetic field in terms of μo at a distance r = 23.1cm from the center of the cable. Express your answer using two decimal places.
