A) \[1.5\times {{10}^{-8}}\,J\]
B) \[2.5\times {{10}^{-7}}\,J\]
C) \[3.5\times {{10}^{-5}}\,J\]
D) \[4.5\times {{10}^{-2}}\,J\]
Correct Answer: A
Solution :
\[U=\frac{1}{2}C{{V}^{2}}=\frac{1}{2}\times 12\times {{10}^{-12}}\times {{(50)}^{2}}\]\[=1.5\times {{10}^{-8}}J\]You need to login to perform this action.
