The number of photo - electrons emitted per second from a metal surface increases when

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
