Answer :

Given, stopping potential =2V

Work function Ф =4.5eV


Wavelength λ=200nm


From Einstein’s photoelectric equation







Minimum kinetic energy of photoelectron is 1.7eV


And maximum kinetic energy


[ Electric potential of 2V is applied for the electrons to


accelerate it is (2+1.7)]
