A) \[8\,\mu \,F\]
B) \[6\,\mu \,F\]
C) \[4\,\mu \,F\]
D) \[3\,\mu \,F\]
Correct Answer: D
Solution :
\[C=\frac{{{\varepsilon }_{0}}A}{d}\] As A ® \[\frac{1}{2}\]times and d ® 2 times So \[C\to \frac{1}{4}\]times i.e. \[{C}'=\frac{1}{4}C=\frac{12}{4}=3\,\mu F\]You need to login to perform this action.
