A phot of energy `h upsilon` is absorbed by a free electron of a metal

1.	A phot of energy `h upsilon` is absorbed by a free electron of a metal having work function `phi lt h upsilon`A. The electron is sure to come outB. The electron is sure to come out with a kinetic energy `(hv-w)`C. Either the electron does not come out or it comes with a kinetic energy `(hv-w)`D. It may come out with a kinetic energy less than `(hv-w)`
Answer» Correct Answer - D Photoelectric effect is a eandom phenomena. So, electron It may come out with a kinetic energy less than `(hv-w)` as some energy is lost while escaping out.
