Splitting & Merging of Drops

A big drop is formed by coalescing 1000 small droplets of water. The surface energy will become:

Show answer and solution

Answer: (b)

Merging $n$ drops: $R = n^{1/3}r$ , so $E_f/E_i = 1/n^{1/3}$ .
$E_f/E_i = 1/(1000)^{1/3} = 1/10$
So the answer is (b) $\frac{1}{10}$ th.
