An oceanographer is studying how the ion concentration in seawater depends on depth. She makes a measurement by lowering into the water a pair of concentric metallic cylinders at the end of a cable and taking data to determine the resistance between these electrodes as a function of depth. The water between the two cylinders forms a cylindrical shell of inner radius outer radius and length L much larger than The scientist applies a potential difference between the inner and outer surfaces, producing an outward radial current I. Let represent the resistivity of the water. Find the resistance of the water between the cylinders in terms of and
