Question

A plane electromagnetic wave of frequency 50 MHz travels in free space along the positive x-direction. At a particular point in space and time, $\vec{E}=6.3 \hat{j} \mathrm{~V} / \mathrm{m}$ The corresponding magnetic field, $\vec{B}$ at that point will be

Select the correct option:

A

$18.9 \times 10^{-8} \hat{\mathrm{k}} \mathrm{T}$

B

$2.1 \times 10^{-8} \hat{\mathrm{k}} \mathrm{T}$

C

$6.3 \times 10^{-8} \hat{\mathrm{k}} \mathrm{T}$

D

$18.9 \times 10^{-8} \hat{\mathrm{k}} \mathrm{T}$
