    In photoelectric emission process from a metal of work function 1.8 eV, the kinetic energy of most energetic electrons is 0.5 eV. The corresponding stopping potential is

    A)  1.3 V         

    B)  0.5 V

    C)  2.3 V        

    D)  1.8 V

    Correct Answer: B

    Solution :

     Stopping potential = Maximum KE \[eV=K{{E}_{\max }}\] So, option  is correct.
