A) \[-1.66\times {{10}^{-16}}\hat{i}\text{ }V/m\]
B) \[1.66\times {{10}^{-16}}\hat{i}\text{ }V/m\]
C) \[-15\text{ \hat{i} }V/m\]
D) \[15\,\,\hat{i}\,\,V/m\]
Correct Answer: D
Solution :
[d] \[\vec{E}=\vec{B}=\vec{C}\] |
\[\therefore \,\,\,\,\,\,\,\left| E \right|=\left| B \right|\cdot C\] |
\[\Rightarrow \,\,\,\,\,\,\,\left| {\vec{E}} \right|=5\times {{10}^{-8}}\times 3\times {{10}^{8}}=15\,\,N/C\] |
\[\vec{E}=15\hat{i}\,\,V\,/\,m\] |
