The work functions of metals A and B are in the ratio 1 : 2 . If light of frequencies f and 2 f are incident on the surfaces of A and B respectively , the ratio of the maximum kinetic energy of photoelectrons emitted is ( f is greater than threshold frequency of A , 2f is greater than threshold frequency of B )
