when a beam of `10.6 eV` photons of intensity `2.0 W//m^(2)` falls on a platinum surface of area `1.0 xx 10^(4) m^(2)` and work  function `5.6 eV , 0.53 %` of  the incidentphotons eject photoelectrons find the number of photoelectrons emited per second and their minimum energies (in eV)Take `1 eV= 1.6 xx 10^(-19) J`
