31. To stop the photoelectric effect induced by irradiation with ultraviolet light platinum records, you need to make a retention potential difference U1 = 3,7 V. If the platinum plate replaced with another plate, the retarding potential difference will have to increase to 6 V. Determine the work and the output of electrons from the surface of the plate.
