So, I should calculate the field at point X due to a ring of charge with radius R, and then assume that I have infinitely many rings? Wouldn't that just lead to the field being infinite? I'm also under the impression that the closer the charge gets to the center of the ring (the second part of...
I'm trying to calculate the electric field due to a hollow cylinder. The cylinder is "semi infinite" with one end at x=0 and the other at - infinity, and radius R. I'm trying to calculate the field at a point x along the axis (not above the end of the cylinder). The cylinder has charge density...
