A photosensitive metallic surface has work function $\phi$. If photon of energy $3 \phi$ falls on the surface, the electron comes out with a maximum velocity of $6 \times 10^6 \mathrm{~m} / \mathrm{s}$. When the photon energy is increased to $9 \phi$, then maximum velocity of photoelectrons will be

$12 \times 10^6 \mathrm{~m} / \mathrm{s}$

$6 \times 10^6 \mathrm{~m} / \mathrm{s}$

$3 \times 10^6 \mathrm{~m} / \mathrm{s}$

$24 \times 10^6 \mathrm{~m} / \mathrm{s}$
