A) \[{{E}_{y}},{{B}_{x}}\]
B) \[{{B}_{y}},{{E}_{z}}\]
C) \[{{E}_{x}},{{B}_{y}}\]
D) \[{{E}_{z}},{{B}_{x}}\]
Correct Answer: C
Solution :
The vectors E,B and k are mutually perpendicular to each other As \[\hat{i}\times \hat{j}=\hat{k}\] So, \[{{E}_{x}}\hat{i}\times {{E}_{y}}\hat{j}=c\hat{k}\] Hence, B is towards\[X-\]direction and B is towards \[Y-\]direction.
