A) \[4.5\times {{10}^{4}}\,N/C\]
B) \[4\times {{10}^{4}}\,N/C\]
C) \[6\times {{10}^{4}}\,N/C\]
D) \[3\times {{10}^{4}}\,N/C\]
Correct Answer: D
Solution :
\[B=100\times {{10}^{-6}}\,\,\sin \left[ 2\pi \times 2\times {{10}^{15}}\left( t-\frac{x}{c} \right) \right]\]Maximum magnetic field \[=\text{ }{{B}_{0}}=100\times {{10}^{-}}^{6}\] Tesla \[{{E}_{0}}=c{{B}_{0}}\] \[{{E}_{0}}=3\times {{10}^{8}}\times 100\times {{10}^{-}}^{6}\] \[=\,\,3\times {{10}^{4}}\,N/C\]
