    The curves (a), (b), (c) and (d) show the variation between the applied potential difference (V) and the photoelectric current (i), at two different intensities of light (I1 > I2). In which figure is the correct variation shown

    A)                                     

    B)                             

    C)                                    

    D)                            

    Correct Answer: B

    Solution :

                       \[{{I}_{1}}>{{I}_{2}}\] (given)           Þ i1 > i2   \[(\because \,i\propto I)\]            and stopping potential does not depend upon intensity. So its value will be same \[({{V}_{0}})\].
