In a typical photon experiment the photon is depicted as moving across the page, say from right to left. Assume we were actually able to witness such an experiment, from the side (to position of reader to a page). If the photon is really moving from left to right can I, standing at 90 degrees to the motion, see the photon?
An uncharged nonconductive hollow sphere of radius 12.0 cm surrounds a 14.0 µC charge located at the origin of a Cartesian coordinate system. A drill with a radius of 1.00 mm is aligned along the z axis, and a hole is drilled in the sphere. Compute t..
