Hi, I need help with this question please
Consider a coaxial cable of length l = 50 cm, inner radius of a = 3 cm, and outer radius of b = 5 cm. Due to the conductivity of σ = 0.05 S/m of the dielectric material, a total current of I = 1 mA flows radially outward between the two conductors. Find:a) the current density as a function of r,b) the electric field between the two conductors as a function of r, c) the voltage between the two conductors.
