    The slope of a graph drawn between threshold frequency and stopping potential is :

    A)  e                                           

    B)  h

    C) \[\frac{h}{e}\]                                  

    D)  he

    Correct Answer: C

    Solution :

                    Relation between threshold frequency \[({{v}_{0}})\] and potential \[{{V}_{0}}\] is \[e{{V}_{0}}=h\,{{v}_{0}}-\phi \] So,     \[{{V}_{0}}=\frac{h}{e}({{v}_{0}})-\frac{\phi }{e}\] Hence, slope of the graph is \[\frac{h}{e}\]
