In the emission of photo-electrons, the number of photo-electrons emitted per unit time depends upon the

The mass of a photo electron is

Light of wavelength 5000 Å and intensity of 3.96 xx 10^(-3) watt//cm^(2) is incident on the surface of photo metal . If 1% of the incident photons only emit photo electrons , then the number of electrons emitted per unit area per second from the surface will be

The kinetic energy of the photo electrons does not depends upon
