Physics Question from JEE Main 2023 · 11 April, Shift 2

A plane electromagnetic wave of frequency 20 MHz20 \, \text{MHz} propagates in free space along xx-direction. At a particular space and time, E⃗=6.6 j^\vec{E} = 6.6 \, \hat{j} v/m. What is B⃗\vec{B} at this point?

  • A

    −2.2×10−8 k^-2.2 \times 10^{-8} \, \hat{k} T

  • B

    −2.2×10−8 i^-2.2 \times 10^{-8} \, \hat{i} T

  • C

    2.2×10−8 k^2.2 \times 10^{-8} \, \hat{k} T

  • D

    2.2×10−8 i^2.2 \times 10^{-8} \, \hat{i} T
