Nature of electromagnetic wave

Question

43 Electromagnetic wave is propagating in x direction. Magnetic field in space is given by $\vec{B} = 2 \times 10^{- 8} \hat{k} T$ . What will be the value and direction of electric field?

Moderate

A

$0.6 \hat{j}$
B

6 $\hat{j}$
C

$0.6 \hat{k}$
D

$6 \hat{k}$

Solution

$E = CB E = 3 \times 10^{8} \times 2 \times 10^{- 8} \Rightarrow E = 6$
The direction of $\vec{v} is \vec{E} \times \vec{B}$
So, $\hat{i} = \hat{j} \times \hat{k}$
