A plane electromagnetic wave of frequency 30 MHz travels in free space along the x-direction. At a particular point in space and time $\vec E = 6.3\hat j\, V/m$. The $\vec B$ at this point would be: |
$2.1 × 10^{-8}\hat k\, T$ $2.1 × 10^{-6}\hat j\,T$ $1.6 × 10^{-8}\hat i\, T$ $2.6 × 10^{-8}\hat j\,T$ |
$2.1 × 10^{-8}\hat k\, T$ |
The correct answer is Option (1) → $2.1 × 10^{-8}\hat k\, T$ |
