In photoelectric effect light of certain frequency `( gt ` threshold frequency ) is incident on a metal surfave whereby , an `e^(-)` ( with certain K.E.) moves towards the collector plate and a flow of current is initiated . In order to stop the current flow, an opposite potential , on the two metal plates, is applied
The work function of a metal is 4eV. If light of frequency `2.3 xx 10^(15) Hz` is incident on metal surface, then
A. No photoelectron will be ejected
B. 2 photoelectron of zero kinetic energy are ejected
C. 1 photoelectron of zero kinetic energy is ejected
D. 1 photoelectron is ejected , which required the stopping potential of 5.52 volt
