A) 6.2
B) 3.8
C) 4.5
D) 8.5
Correct Answer: D
Solution :
\[C=\frac{A{{\in }_{0}}K}{d}\And V=Ed\] \[\Rightarrow \] \[C=\frac{A{{\in }_{0}}KE}{V}\] \[K=\frac{CV}{A{{\in }_{0}}E}=\frac{(15\times {{10}^{-12}})(500)}{{{10}^{-4}}(8.86\times {{10}^{-12}})({{10}^{16}})}\]You need to login to perform this action.
