Two surfaces are near two different charged objects, and the surfaces are identical in size. Surface A has N field lines passing perpendicularly through it. Surface B has only N/2 field lines passing through it, and they pass through at an angle 68ยฐ from normal. By how much does the field line density greater near surface B than near surface A?
