    Which one of the following is the graph between frequency v of the incident radiation and stopping potential?

    A)

    B)

    C)  

    D)

    Correct Answer: B

    Solution :

                     From Einsteins photoelectric equation, the stopping potential \[{{V}_{0}}\] is given by                 \[{{V}_{0}}=\frac{hv}{e}-\frac{h{{v}_{0}}}{e}\] where \[{{v}_{0}}\] is threshold frequency. Hence, correct variation is shown by graph .
