The threshold frequency for a certain metal is ' \(v_0\) '. When a certain radiation of frequency \(2 v_0\) is incident on this metal surface, maximum velocity of the photo electrons emitted is \(2 \times 10^6 \mathrm{~ms}^{-1}\). If radiation of frequency \(3 v_0\) is incident on the same metal surface, the maximum velocity of the photo electrons emitted is ____
- A \(\sqrt{2} \times 10^{-6} \mathrm{~ms}^{-1}\)
- B \(2 \sqrt{2} \times 10^6 \mathrm{~ms}^{-1}\)
