Question

A material of resistivity ρ is formed into a solid, truncated cone of height h and radii r 1 and r2 at either end (see the figure (Figure 1)). 

Part A Calculate the resistance of the cone between the two flat end faces. (Hint: Imagine slicing the cone into very many thin disks, and calculate the resistance of one such disk.) Express your answer in terms of the variables ρ, h, r 1, r 2 and appropriate constants.
