A plane electromagnetic wave of frequency $25 \mathrm{MHz}$ travels in a free space along the $x$-direction. At the particular point in space and time, $\mathbf{E}=63 \hat{\mathbf{j}} \mathrm{V} / \mathrm{m}$. What is $\mathbf{B}$ at that point? (a) $2.1 \times 10^{-8} \hat{k T}$ (b) $3.1 \times 10^{-5}$ \hat{kT } (c) $5.0 \times 10^{-6} \hat{\mathrm{k} T}$ (d) 0

Round 1
A plane electromagnetic wave of frequency $25 \mathrm{MHz}$ travels in free space along the $\mathrm{x}$ direction. At a particular point in space and time $\mathrm{E}^{-}=6.3 \mathrm{j} \wedge \mathrm{Vm}^{-1}$ then $\mathrm{B}^{-}$ at this point is (A) $2.1 \times 10^{-8}$ i $\mathrm{T}$ (B) $2.1 \times 10^{-8} \mathrm{k} \wedge \mathrm{T}$ (C) $1.89 \times 10^{9} \mathrm{k} \wedge \mathrm{T}$ (D) $2.52 \times 10^{-7} \mathrm{k} \wedge \mathrm{T}$
