Electrons with a kinetic energy of $6.023 \times 10^4 \;j/mol$ are evolved from a surface of a metal , when it is exposed to radiation of wavelength of $600\;nm$. The minimum amount of energy required to removed an electron from the metal atom is:

\[\begin {array} {1 1} (1)\;2.3125 \times 10^{-19}\;J & \quad (2)\;3 \times 10^{-19}\;J\\ (3)\;6.02 \times 10^{-19}\;J & \quad (4)\;6.62 \times 10^{-34} \end {array}\]
