Electrostatics + Magneotostatics HW question

1. For a coaxial cable, calculate E, D, H, and B everywhere assuming a uniform current I in both conductors and uniform charge per unit length on both conductors. Then find: inductance and capacitance per unit length, leakage resistance across the dielectric per unit length, and conductor resistance per unit length.



2. Assume: Copper conductors
Polyethylene insulator
Inner conductor diameter: 2mm
Outer conductor diameter: 4mm
Outer conductor thickness: 0.2mm




3. All I know is we can consider the outer conducter to be infinately thin, DC currect is uniform, and we can consider air to be everywhere.

This is a large problem and could use any assistance in figuring each part out. Not really sure how to start any of the parts I am to answer.
