  • question_answer
    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)  1.3V                                     

    B)  0.5V                     

    C)         2.3V                     

    D)         1.8V

    Correct Answer: B

    Solution :

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