Question

In a photoelectric effect experiment if f is the frequency of radiations incident on the metal surface and I is the intensity of the incident radiations then choose the correct statement s A If f is increased keeping I and work function constant then maximum kinetic energy of photoelectron increases B If distance between cathode and anode is increased stopping potential increases C If I is increased keeping f and work function constant then stopping potential remains same and saturation current increases D Work function is decreased keeping f and I constant then stopping potential increases Select correct alternative 1 A B C 2 B C D 3 A C D
