\begin{aligned} & \frac{E_{r m s}}{B_{r m s}}=c \\ & B_{r m s}=\frac{E_{r m s}}{c} =\frac{6}{3 \times 10^8} \\ & B_{\mathrm{rms}}=2 \times 10^{-8} \\ & B_{r m s}=\frac{B_0}{\sqrt{2}} \\ & B_0=\sqrt{2} \times B_{r m s} \\ & =\sqrt{2} \times 2 \times 10^{-8} \\ & =2.83 \times 10^{-8} \mathrm{~T} \end{aligned}
