A long non-conducting hollow cylinder with inner radius, ri and outer radius, r2 is charged with a uniform positive charge with a charge density ?. (a) Use Gauss's Law in differential form for regions outside the cylinder (r >r2) to show that the electric field decreases as 1/r (note that no marks will be awarded for using Gauss's Law in integral form).
