A) \[240pF\]
B) \[240\mu F\]
C) \[240F\]
D) None of the above
Correct Answer: A
Solution :
\[C=4\pi {{\varepsilon }_{0}}K\,\left[ \frac{ab}{b-a} \right]=\frac{1}{9\times {{10}^{9}}}.6\,\left[ \frac{12\times 9\times {{10}^{-4}}}{3\times {{10}^{-2}}} \right]\] \[=24\times {{10}^{-11}}=240\,pF\]You need to login to perform this action.
