In a photoelectric experiment a parallel beam of monochromatic light with power of 200 W is incident on a perfectly absorbing cathode of work function 6 25 eV The frequency of light is just above the threshold frequency so that the photoelectrons are emitted with negligible kinetic energy Assume that the photoelectron emission efficiency is 100 A potential difference of 500 V is applied between the cathode and the anode All the emitted electrons are incident normally on the anode and are absorbed The anode experiences a force F n x 10 N due to the impact of the electrons The value of n is Mass of the electron 10 31 kg and 10 1610 18 1
