Dual Nature of Radiation and Matter

Question: A photosensitive metallic surface has work function $h{v_0}$. If photons of energy fall on this surface the electrons come out with a maximum velocity of $4 \times {10^6}\,m/s$. When the photon energy is increases to $5h{v_0}$ then maximum velocity of photo electron will be


1) $2 \times {10^6}\,m/s$
2) $2 \times {10^7}\,m/s$
3) $8 \times {10^5}\,m/s$
4) $8 \times {10^6}\,m/s$
Solution: Explanation: No Explanation
