Properties Of Solids And Liquids Question 333
Question: A spherical liquid drop of radius R is divided into eight equal droplets. If surface tension is T, then the work done in this process will be [CPMT 1990]
Options:
A) 2$ \pi R^{2}T $
B)3$ \pi R^{2}T $
C) 4$ \pi R^{2}T $
D)2$ \pi RT^{2} $
Show Answer
Answer:
Correct Answer: C
Solution:
$ W=4\pi R^{2}T({{r}^{1/3}}-1)=4\pi R^{2}T({{8}^{1/3}}-1)=4\pi R^{2}T $
