Question

When light of frequency twice the threshold frequency is incident on the metal plate, the maximum velocity of emitted election is $v_1$. When the frequency of incident radiation is increased to five times the threshold value, the maximum velocity of emitted electron becomes $v_2$. If $v_2=x v_1$, the value of $x$ will be
