When the light of frequency 2v o (where v o threshold frequency), is incident on a metal plate, the maximum velocity of electrons emitted is v 1 When the frequency of the incident radiation is increased to 5v o , the maximum velocity of electrons emitted from the same plate is v 2 . The ratio of v 1 to v 2 is
