The electric field in an electromagnetic wave is given by { {\E}}^{\to}=\stackrel{\^}{ {\i}} 40 \cos \omega ( {\t}- { {\z}}/{ {\c}}) N C^{-1}. The magnetic field induction of this wave is (in SI unit): [4 Apr 2024 Shift 1]

Correct Answer is : →B=^j40ccosω(t−zc)

{ {\B}}^{\to}=\stackrel{\^}{ {\i}} \frac{40}{ {\c}} \cos \omega ( {\t}- { {\z}}/{ {\c}})

\overrightarrow{B}=\stackrel{\^}{j} 40 \cos \omega (t-\frac{z}{c})

{ {\B}}^{\to}=\stackrel{\^}{ {\k}} \frac{40}{ {\c}} \cos \omega ( {\t}- { {\z}}/{ {\c}})

\overrightarrow{B}=\stackrel{\^}{j} \frac{40}{c} \cos \omega (t-\frac{z}{c})
