long coaxial cable consists of an inner cylindrical conductor with radius a and an outer coaxial cylinder with inner radius b and outer radius c . The outer cylinder is mounted on insulating supports and has no net charge. The inner cylinder has a uniform positive charge per unit length λ . Part A Calculate the magnitude of the electric field at any point between the cylinders a distance r from the axis. Express your answer in terms of the variables a , b , c , r , λ and constants π and ϵ 0 . Part C Calculate the magnitude of the electric field at any point outside the outer cylinder a distance r from the axis. Express your answer in terms of the variables a , b , c , r , λ and constants π and ϵ 0 . Part E Find the charge per unit length on the inner surface and on the outer surface of the outer cylinder. Enter your answers in ascending order separated by a comma.
