A metal plate of area 1 10^–4 m² is illuminated by a radiation of intensity 16 mW/m². The work function of the metal is 5 eV. The energy of the incident photons is 10 eV and only 10% of it produces photo electrons.
The number of emitted photoelectrons per second and their maximum energy, respectively, will be
