A) \[6\times {{10}^{-8}}tesla\]
B) \[3\times {{10}^{-8}}tesla\]
C) \[12\times {{10}^{-8}}tesla\]
D) \[9\times {{10}^{-8}}tesla\]
Correct Answer: A
Solution :
Amplitude of electric field\[{{E}_{0}}=18\,\,V/m\] The magnitude of the oscillating magnetic field \[{{E}_{0}}=\frac{{{E}_{0}}}{c}=\frac{18}{3\times {{10}^{8}}}=6\times {{10}^{-8}}tesla\]You need to login to perform this action.
