QUESTION: 8

Photon of 5.5eV energy fall on the surface of the metal emitting photoelectrons of maximum kinetic energy 4.0eV. The stopping voltage required for these electrons are

Solution:

Energy of photon is 5.5 eV and the maximum kinetic energy of the photo electrons is 4 eV.

The maximum kinetic energy is given by :

Emax = eVo

Vo is stopping potential

4 eV = eVo

Vo = 4V

So, the stopping  voltage required for these electrons is 4 volt.
