When the light of frequency 2v₀ (where v₀ isthreshold frequency), is incident on a metalplate, the maximum velocity of electronsemitted is v₁. When the frequency of theincident radiation is increased to 5v₀, themaximum velocity of electrons emitted fromthe same plate is v₂. The ratio of v₁ to v₂ is
(1) 4 : 1 (2) 1 : 4
(3) 1 : 2 (4) 2 : 1
