The electric field due to an infinitely long, straight line of charge with uniform charge density λ points straight away from the line and has magnitude E=λ/2πε0r, where r is the distance from the wire. Calculate the flux of this electric field through a right cylinder of height h and radius R, co-axial with the charged line. Repeat the calculation for a cylinder of radius 2 R.
