A) \[13.29\times {{10}^{-12}}\]
B) \[8.86\times {{10}^{-12}}\]
C) \[17.72\times {{10}^{-12}}\]
D) \[4.43\times {{10}^{-12}}\]
E) \[2.22\times {{10}^{-12}}\]
Correct Answer: B
Solution :
\[U=\frac{1}{2}\times \frac{1}{2}{{\varepsilon }_{0}}{{E}^{2}}=\frac{1}{2}\times \frac{1}{2}\times 8.85\times {{10}^{-12}}\times {{(2)}^{2}}\] \[=8.85\times {{10}^{-12}}J{{m}^{-3}}\]You need to login to perform this action.
