Electrostatics Question 143
Question: A spherical drop of capacitance 1 mF is broken into eight drops of equal radius. Then, the capacitance of each small drop is …… [KCET 2004]
Options:
A) $ \frac{1}{8}\mu F $
B) $ 8\mu F $
C) $ \frac{1}{2}\mu F $
D) $ \frac{1}{4}\mu F $
Show Answer
Answer:
Correct Answer: C
Solution:
Using $ C={{n}^{1/3}}c $
therefore $ c=\frac{C}{{{n}^{1/3}}}=\frac{C}{{{(8)}^{1/3}}}=\frac{C}{2} $
$ =\frac{1}{2}\mu F $
