Splitting & Merging of Drops

The surface energy of a liquid drop is 'U'. It splits up into 512 equal droplets. The surface energy becomes

Show answer and solution

Answer: (a)

Splitting into $n$ equal droplets: $r = R/n^{1/3}$ , $U_f = n^{1/3}U$ .
$U_f = (512)^{1/3}U = 8U$
So the answer is (a) 8 U.
