Dot product of two parallel vectors.

The vector product of two vectors is a vector perpendicular to both of them. Its magnitude is obtained by multiplying their magnitudes by the sine of the angle between them. The direction of the vector product can be determined by the corkscrew right-hand rule. The vector product of two either parallel or antiparallel vectors vanishes. From the definition of the cross product, we find that the cross product of two parallel (or collinear) vectors is zero as the sine of the angle between them (0 or 1 8 0 ∘) is zero.Note that no plane can be defined by two collinear vectors, so it is consistent that ⃑ 𝐴 × ⃑ 𝐵 = 0 if ⃑ 𝐴 and ⃑ 𝐵 are collinear..
