9.6 Exercise 9

A coaxial cable consists of an inner conductor with radius $r_{\text{i}} = 0.25 \text{cm}$ and an outer radius of $r_{\text{o}} = 0.5 \text{cm}$ and has a length of 10 meters. Plastic, with a resistivity of $\rho = 2.00 \times 10^{13} \Omega \cdot \text{m}$, separates the two conductors. What is the resistance of the cable?
