Question

5. Consider two coaxial metal cylinders of radii a and b, where b > a. (a) Suppose that the inner cylinder carries a charge per unit length of Q/L. What is the electric field in the region a < s < b? (b) Use your answer to calculate the potential difference between the two cylinders, i.e. compute V(b) - V(a). (c) Now find the capacitance per unit length of the coaxial cable. Does your answer depend on Q or \DeltaV?
