    A long charged cylinder of linear charged density  is surrounded by a hollow co-axial conducting cylinder. What is the electric field in the space between the two cylinders?  

    Answer:

    Consider a cylinder having charge density                   Electric flux is given by                  of curved surface of cylinder of radius r and length                 i.e.,                    According to Gauss? law,                                                 i.e.
