A) \[1.11\times {{10}^{-12}}\,C\]
B) \[9.11\times {{10}^{-12}}\,C\]
C) \[7.11\times {{10}^{-6}}\,C\]
D) None of these
Correct Answer: A
Solution :
\[E=9\times {{10}^{9}}\frac{Q}{{{r}^{2}}}\]Þ \[Q=\frac{E\times {{r}^{2}}}{9\times {{10}^{9}}}=\frac{1\times {{(0.1)}^{2}}}{9\times {{10}^{9}}}=1.11\times {{10}^{-12}}C\]You need to login to perform this action.
