Answer :

Given, work function Ф =2 eV


Solving the above equation using formula,




From the above equation there are two values of W



for maximum kinetic energy W should be maximum


=


And also from Einstein’s photoelectric equation,




Kinetic energy will be maximum when f (frequency) is


Maximum and f will be maximum when W is maximum.




K= 3.93 eV.
