A) \[4.23\times {{10}^{-8}}T\]
B) \[1.41\times {{10}^{-8}}T\]
C) \[2.83\times {{10}^{-8}}T\]
D) \[0.70\times {{10}^{-8}}T\]
Correct Answer: C
Solution :
[c] \[\frac{{{E}_{rms}}}{{{B}_{rms}}}=c\] |
\[{{B}_{rms}}=\frac{{{E}_{rms}}}{c}\] |
\[=\frac{6}{3\times {{10}^{8}}}\] |
\[{{B}_{rms}}=2\times {{10}^{-8}}\] |
\[{{B}_{rms}}=\frac{{{B}_{0}}}{\sqrt{2}}\] |
\[{{B}_{0}}=\sqrt{2}\times {{B}_{rms}}\] |
\[=\sqrt{2}\times 2\times {{10}^{-8}}\] |
\[=2.83\times {{10}^{-8}}T\] |
