Splitting & Merging of Drops

1000 small water drops of equal size combine to form a big drop. The ratio of final surface energy to the total initial surface energy is

Show answer and solution

Answer: (b)

  1. Merging nn drops: R=n1/3rR = n^{1/3}r, so Ef/Ei=1/n1/3E_f/E_i = 1/n^{1/3}.
  2. Ef/Ei=1/10E_f/E_i = 1/10
  3. So the answer is (b) 1:101:10.
