    A spherical drop of mercury having a potential of 2.5 V is obtained as a result of merging 125 droplets. The potential of constituent droplets would be                          [Orissa JEE 2003]

    A)            1.0 V                                        

    B)            0.5 V

    C)            0.2 V                                        

    D)            0.1 V

    Correct Answer: D

    Solution :

               \[V={{n}^{2/3}}v\]Þ \[2.5={{(125)}^{2/3}}v\] Þ \[V=\frac{2.5}{25}=0.1\,volt\]
