Structure of Atom

238725 Electrons with a kinetic energy of $6.023 \times 10^4 \mathrm{~J} /$ mol are evolved from the surface of a metal, when it is exposed to radiation of wavelength of $600 \mathrm{~nm}$. The minimum amount of energy required to remove an electron from the metal atom is

1 $2.3125 \times 10^{-19} \mathrm{~J}$
2 $3 \times 10^{-19} \mathrm{~J}$
3 $6.02 \times 10^{-19} \mathrm{~J}$
