• question_answer1) When photons of wavelength \[{{\lambda }_{1}}\], are incident on an isolated sphere, the corresponding stopping potential is found to be V. When photons of wavelength \[{{\lambda }_{2}}\]are used , the corresponding stopping potential was thrice that of the above value. If light of wavelength \[{{\lambda }_{3}}.\]is used then find the stopping potential for this case   JEE Main Online Paper (Held On 09 April 2016)
  A)
  \[\frac{hc}{e}\left[ \frac{1}{{{\lambda }_{3}}}+\frac{1}{2{{\lambda }_{2}}}-\frac{3}{2{{\lambda }_{1}}} \right]\]
