Splitting & Merging of Drops

Determine the ratio of surface energy of $1$ large drop to $1$ small drop, if $1000$ small drops combined to form $1$ large drop.

Show answer and solution

Answer: (a)

$1000\, r^3 = R^3 \Rightarrow R = 10r$ .
Surface energy $\propto$ radius $^2$ : $\frac{E_{large}}{E_{small}} = \frac{R^2}{r^2} = 100$
So the answer is (a) $100 : 1$ .
