Splitting & Merging of Drops

A liquid drop having surface energy ' $E$ ' is spread into 512 droplets of same size. The final surface energy of the droplets is

Show answer and solution

Answer: (c)

Splitting into $n$ equal droplets: $E_f = n^{1/3}E$ .
$E_f = (512)^{1/3}E = 8E$
So the answer is (c) 8 E.
