Given that a photon of light of wavelength 10,000 angstrom has an energy equal to `1.23eV`. When light of wavelengths 5000 angstrom and intensity `I_(0)` falls on a photoelectric cell, the saturation current is `0.40 xx 10^(-6)` ampere and the stopping potential is 1.36 volt, then the work function is-
