Question: Capacitance (in F) of a spherical conductor with radius 1m is [AIEEE 2002]
Options:
A) $ 1.1\times {{10}^{-10}} $
B) $ {{10}^{-6}} $
C) $ 9\times {{10}^{-9}} $
D) $ {{10}^{-3}} $
Show Answer
Answer:
Correct Answer: A
Solution:
$ C=4\pi {\in _{0}}R=\frac{1}{9\times 10^{9}}\times 1=1.1\times {{10}^{-10}}F $
