What is the stopping potential when the metal with work function 0.6 eV is illuminated with the light of 2 eV
2.6 V
3.6 V
0.8 V
1.4 V
V0=(E−W0)e=(2eV−0.6eV)e=1.4V
The light rays having photons of energy 1.8 eV are falling on a metal surface having a work function 1.2 eV. What is the stopping potential to be applied to stop the emitting electrons
