Splitting & Merging of Drops

A liquid drop having surface energy EE is spread into 729 droplets of same size. The final surface energy of the droplets is

Show answer and solution

Answer: (b)

  1. Splitting into nn equal droplets: Ef=n1/3EE_f = n^{1/3}E.
  2. Ef=(729)1/3E=9EE_f = (729)^{1/3}E = 9E
  3. So the answer is (b) 9 E.
