A) \[1.77\times {{10}^{12}}{{C}^{2}}{{N}^{1}}{{m}^{2}}\]
B) \[0.44\times {{10}^{10}}{{C}^{2}}{{N}^{1}}{{m}^{2}}\]
C) \[5.00\text{ }{{C}^{2}}{{N}^{1}}{{m}^{2}}\]
D) \[0.44\times {{10}^{13}}{{C}^{2}}{{N}^{1}}{{m}^{2}}\]
Correct Answer: B
Solution :
[b] \[C=K{{C}_{0}}\] |
\[K=\frac{C}{{{C}_{0}}}=\frac{30}{6}=5\] |
\[K=\frac{\varepsilon }{{{\varepsilon }_{0}}}\] |
\[\varepsilon =K{{\varepsilon }_{0}}\] |
\[=5\times 8.85\times {{10}^{-12}}\] |
\[=0.44\times {{10}^{-10}}{{C}^{2}}{{N}^{-1}}{{m}^{-2}}\] |
