Find the electric field E and electrostatic potential V for a long hollow cylindrical tube which carries a uniform surface charge density σ. Explicitly compute the discontinuity in E, and the discontinuity in the normal derivative of V, at the surface of the cylinder, and show that these results are consistent with the general results of Griffiths Eq. (2.33) and (2.36).
