    Several spherical drops of a liquid of radius r coalesce to form a single drop to radius R. If T is surface tension and V is volume under consideration, then the release of energy is

    A) \[\frac{7}{2}\]                   

    B) \[\frac{{{x}^{2}}}{9}+\frac{{{y}^{2}}}{5}=1\]

    C) \[\frac{27}{4}\]                

    D) \[\frac{27}{2}\]

    Correct Answer: B

    Solution :

    Energy released \[3VT\left( \frac{1}{r}+\frac{1}{R} \right)\] \[3VT\left( \frac{1}{r}-\frac{1}{R} \right)\]
