What is ratio of surface energy of 1 small drop and 1 large drop, if 1000 small drops combined to form 1 large drop
Text Solution
Verified by ExpertsThe correct answer is:
D
Volume of liquid remain same i.e. volume of 1000 small drops will be equal to volume of
one big drop
$n \frac{4}{3} \pi r^{3} = \frac{4}{3} \pi R^{3} \Rightarrow 1000 r^{3} = R^{3} \Rightarrow R = 10 r \therefore \frac{r}{R} = \frac{1}{10}$ $\frac{\text{surface energy of one small drop}}{\text{surface energy of one big drop}} = \frac{4 \pi r^{2} T}{4 \pi R^{2} T} = \frac{1}{100}$
