The figure below depicts the cross section of an infinitely long cylindrical shell concentric with an infinitely long cylindrical wire.
a) What is the electric field between the two cylinders (a < r < b)? (Hint: Use Gauss's Law)
b) What is the electric field outside of both of the cylinders (r > c)?
