If |A×B|=3 , and each of And and B is parallel to the plane YZ , Find A×B A×B is Cross product of vectors

Question

If $|A×B|=3$ , and each of $A$ And and $B$ is parallel to the plane $YZ$ , Find $A×B$

$A×B$ is Cross product of vectors

Answer 1

$A\times B$ is parallel to $X$ axis and as its module is $3$ it can be

$(3,0,0)$ or $(-3,0,0)$
