How do I apply Gauss''s law to coaxial conducting cylinders?
NEver forget that Gauss law talks about the electric flux. The flux does not vary wether there is a wire or a cylinder. However, if you want to extract the electric field from the flux, you need the distribution to be symmetric. In this case, it is correctly symmetric, so that the electric field has the same value along the whole surface.
