Task 50368.

Monochromatic ultraviolet light with a wavelength of 50 nm falls on the aluminum plate, tearing out electrons from it. The red border of the photoelectric effect is 9 * 1014 Hz. Determine the maximum possible removal of the l electron from the surface of the plate, if the strength of the retarding electric field is E = 500 V / m.
