A metal plate is placed 2 m away from a monochromatic light source of 2mW power. Assuming that an electron in metal collects is energy for ma circular area of the plate as large as 10 atomic diameters (10m) in radius, determine how much time it will take for such a target to soak off 5 eV of energy for its emission from the metal?
