    If 1000 droplets each of potential IV and radius r are mixed to form a big drop. Then, the potential of the drop as compared to small droplets, will be

    A) 1000V                   

    B) 800V

    C) 100V   

    D) (d) 20V

    Correct Answer: C

    Solution :

    The potential of the big drop \[{{\left( {{\text{t}}_{\text{1/2}}} \right)}_{2}}=0.8s,{{a}_{2}}=50\]                   (a) = 100 V
