4. A coaxial transmission line has inner and outer conductor radii a and b as shown in Figure 3. Between conductors (a < p < b) lies a conductive medium whose conductivity is olp) = ov/p, where o is a constant. The inner conductor is charged to potential Vo, and the outer conductor is grounded. (4a) Assuming de radial current I per unit length in z, determine the radial current density field J in A/m². (4b) Determine the electric field intensity E in terms of I and other parameters. (4c) By taking an appropriate line integral of E as found in part (4b), find an expression that relates Vo to I.
