JEE MainPhysicsElectromagnetic WavesMCQ+4 / −1
A plane electromagnetic wave of frequency 35 MHz35 \mathrm{~MHz}35 MHz travels in free space along the XXX-direction. At a particular point (in space and time) E⃗=9.6j^ V/m\vec{E}=9.6 \hat{j} \mathrm{~V} / \mathrm{m}E=9.6j^​ V/m. The value of magnetic field at this point is :
  1. A
    9.6j^T9.6 \hat{j} T9.6j^​T
  2. B
    3.2×10−8i^T3.2 \times 10^{-8} \hat{i} T3.2×10−8i^T
  3. C
    9.6×10−8k^T9.6 \times 10^{-8} \hat{k} T9.6×10−8k^T
  4. D
    3.2×10−8k^T3.2 \times 10^{-8} \hat{k} T3.2×10−8k^T
