A) \[2.83\times {{10}^{-8}}T\]
B) \[0.70\times {{10}^{-8}}T\]
C) \[4.23\times {{10}^{-8}}T\]
D) \[1.41\times {{10}^{-8}}T\]
Correct Answer: A
Solution :
Given, \[{{E}_{rms}}=6V/m\] \[\frac{{{E}_{rms}}}{{{B}_{rms}}}=c\Rightarrow {{B}_{rms}}=\frac{{{E}_{rms}}}{c}\] ?.(i) \[{{B}_{rms}}=\frac{{{B}_{0}}}{\sqrt{2}}\Rightarrow {{B}_{0}}=\sqrt{2}{{B}_{rms}}\] \[{{B}_{0}}=\sqrt{2}\times \frac{{{E}_{rms}}}{C}\]From equation (i) \[=\frac{\sqrt{2}\times 6}{3\times {{10}^{8}}}=2.83\times {{10}^{-8}}T\]
