15 Consider a monochromatic linear source of light which is placed at a distance of r from a very small metal plate Due to photoelectric effect electrons are ejected at rate N per second and it is found that maximum kinetic energy of photoelectron is K If source is brought closer to a the rate of emission and the r distance maximum kinetic energy of of photoelectron become nearly 1 F 3K 3 3N K 3 2 3N 3K 4 3N K
