When photons of energy $5 \mathrm{eV}$ incident on a photo metal of work function $4.36 \mathrm{eV}$, photo electrons are emitted. The maximum impulse of the metal surface is
  1. $2.41 \times 10^{-25} \mathrm{kgms}^{-1}$
  2. $2.31 \times 10^{-25} \mathrm{kgms}^{-1}$
  3. $4.31 \times 10^{-25} \mathrm{kgms}^{-1}$
  4. $1.31 \times 10^{-24} \mathrm{kgms}^{-1}$
