technically your question is wrong.
you cannot do a dot product with a scalar value => |A x B| will turn to be a scalar because you are taking its mod.
question should be (A x B).B , all being vectors.
it should be zero.
A x B will produce a vector perpendicular to both A and B. and dot product with something perpendicular is zero.
