When photon of energy 4.0 eV strikes the surface of a metal A , the ejected photoelectrons have maximum kinetic energy 
and de-Broglie wavelength 
. The maximum kinetic energy of photoelectrons liberated from another metal 
by photon of energy 4.50 eV is 
. If the de-Broglie wavelength of these photoelectrons 
, then the work function of metal 
is:
