5. Two long coaxial metal cylinders with radii a and b are separated by material of
conductivity o (see figure below). The conductivity is not uniform and changes as
= (s)0
where k is a constant. If the two cylinders are kept at a potential difference V,
find the resistance R between the cylinders.

Hint: Since the conductivity is a function of position, the charge density in the resistive
medium is not zero and E does not go like 1/s. However, since the current I is steady, the
same current flows across each eylindrical surface. Instead of using Gauss' Law, find E
in terms of I, from Ohm's Law.
