When a certain radiation of frequency `2v_(0)` is incident on this metal surface the maximum velocity of the photoelectrons emitted is `2xx10^(6)ms^(-1)`. If a radiation of frequency `3v_(0)`, is incident on the same metal surface the maximum velocity of the photoelectrons emitted (in `m.s^(-1)` ) is
