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 metal is 6eV . If light of frequency  1 xx 10^(15) Hz is incident on the metal , intensity of light is increased 4 times, then
A. No photoelectron will be ejected
B. 8 photoelectrons of zero kinetic energy shall be ejected
C. 2 photoelectrons of 2 eV kinetic energy are ejected
D. Only one photoelectron is ejected
