  • question_answer
    The maximum kinetic energy of photo electrons emitted from a surface when photons of energy 6eV fall on it is 4eV. The stopping potential is (in V)

    A)  2                                

    B)  4

    C)  6                                

    D)  10

    Correct Answer: B

    Solution :

    The potential applied to stop the electrons having maximum kinetic energy is the stopping potential. Hence its value will be 4V
