A coaxial cable consists of a solid inner conductor of radius R1 surrounded by a concentric cylindrical tube of inner radius R2 and outer radius R3 (the figure). The conductors carry equal and opposite currents I0 distributed uniformly across their cross sections. (Figure 1) e) Let I0=1.50A, R1=1.00 cm, R2=2.00 cm, and R3=2.50 cm. Graph Bfrom R=0 to R=3.00 cm.
