A metal having a threshold frequency of ...

A metal having a threshold frequency of `v_0//2` is illuminated by the incident radiation of frequency `2v_0` . If the energy of the incident photon is increased by 40 percent , then what will be the percentage change in the kinetic energy of the photoelectrons emitted from the surface of the metal ? Note that increase in energy of photon is done by suitably changing frequency of radiation.
