A long, straight wire is surrounded by a hollow metal cylinder whose axis coincides with that of the wire. The wire has a charge per unit length of λ, and the cylinder has a net charge per unit length of 2λ. From this information, use Gauss's law to find the following. (Use any variable or symbol stated above along with the following as necessary: ε0 and π.) (a) the charge per unit length on the inner surface of the cylinder λinner = (b) the charge per unit length on the outer surface of the cylinder λouter = (c) the electric field outside the cylinder a distance r from the axis magnitud
