Question

1. ("Photoelectric effect in magnetic field") A small metallic ball is suspended at the center of a cylindrical glass vessel of radius R. A monochromatic light of frequency the surface of the ball, and the photo-electrons are being emitted. The inside of the vessel is in high vacuum, and the inner wall of the side of the cylinder is coated with phosphorus, so that it glows when the photo-electrons are able to reach it (a) Under these conditions, what is the maximal kinetic energy of the photo-electrons? The work function of the metal is Light illuminating the ball A metallic ball in the center of a cylinder Photo-electron reaching the side of the cylinder (side still glowing)
