Given that a photon of light of wavelength 10,000 Å has an energy equal to 1.23 eV. When light of wavelength 5000 Å and intensity Io falls on a photoelectric cell,the saturation current is 0.40 x 10-6 A and the stopping potential is 1.36 V; if the intensity of light is made 4I0, then the saturation current will become
