A beam of photons of energy 5.0 eV is incident on a metal surface, whose work function is 3.0 eV. The metal remains isolated and the photoelectrons are being removed instantaneously after their emission. Although photoelectric emission akes places initially, but after some times it ceases. Explain it with reasons.
