Suppose you have an infinite non-conducting cylinder of charge of radius R, and uniform charge density lambda. Starting from Gauss' Law, show: that the Electric Field inside is given by: E = lambda r/2 pi epsilon_o R^2 the Electric Field outside is given by E = lambda/2 pi epsilon_o r A big part of your grade will depend on how accurate and detailed your picture is, and how clean and clear your resulting derivation is.
Problem 5 Compute the total charge inside in a cylinder of length h and radius Rcy, when ρ(R) αR. Use the result to compute the electric field produced by the cylinder at points outside the cylinder (rRcyl). Note that since > Rcyl, the Gaussian surface (with radius r) encloses all the charge in the cylinder. State the direction of the electric field inside and outside the cylinder when a > 0, that is, when the cylinder carries positive charge. Problem...
