Splitting & Merging of Drops

The surface energy of a liquid drop is ' $V$ '. It is sprayed into 1000 equal droplets. The surface energy of all the droplets is

Show answer and solution

Answer: (b)

Splitting into $n$ equal droplets: $r = R/n^{1/3}$ , so $E_f = n \cdot \dfrac{1}{n^{2/3}} V = n^{1/3}V$ .
$E_f = (1000)^{1/3}V = 10V$
So the answer is (b) 10 V.
