A) \[16\times {{10}^{-32}}\text{J}\]
B) \[3.1\times {{10}^{-26}}\text{J}\]
C) \[4\times {{10}^{-10}}\text{J}\]
D) \[32\times {{10}^{-32}}\text{J}\]
Correct Answer: D
Solution :
\[W=\frac{1}{2}\frac{{{q}^{2}}}{C}\] \[=\frac{1}{2}\times \frac{{{(8\times {{10}^{-18}})}^{2}}}{100\times {{10}^{-6}}}\] \[=\frac{1}{2}\times \frac{64\times {{10}^{-36}}}{100\times {{10}^{-6}}}\] \[=32\times {{10}^{-32}}J\]
