Q. A spherical drop of capacitance $1\ \mu F$ is broken into eight drops of equal radius. Then, the capacitance of each small drop is ……
A) $\frac{1}{8}\mu F$
B) $8\mu F$
C) $\frac{1}{2}\mu F$
D) $\frac{1}{4}\mu F$
Explanation
(c) Using $C = n^{1/3}c \Rightarrow c = \frac{C}{n^{1/3}} = \frac{C}{(8)^{1/3}} = \frac{C}{2} = \frac{1}{2}\mu F$
