Question

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.
• B.
• C.
• D.

Answer 1

The correct option is C

Using
$C=n^{1/3}{C}^{{}^{\prime }}\Rightarrow C^{{}^{\prime }}=\frac{C}{n^{1/3}}=\frac{1\mu F}{(8{)}^{1/3}}=\frac{1}{2}\mu F$
