In a photoelectric experiment, the collector plate is at 2.0V with respect to the emitter plate made ofcopper phi = 4.5eV). The emitter is illuminated by a source of monochromatic light of wavelength 200nm.
(A) the minimum kinetic energy of the photoelectrons reaching the collector is 0.
(B) the maximum kinetic energy of the photoelectrons reaching the collector is 3.7eV.
(C) if the polarity of the battery is reversed then answer to part A will be 0.
(D) if the polarity of the battery is reversed then answer to part B will be 1.7eV.
