One thousand small water drops of equal radii combine to form a big drop. The ratio of final surface energy to the total initial surface energy is
1000 : 1
1 : 1000
10 : 1
1 : 10
As volume remains constant therefore R = n13r
surface energy of one big dropsurface energy of n drop = 4πR2Tn×4πr2T
R2nr2 = n23nr2 = 1n13 = 1(1000)13 = 110
