Jul 20, 2022 · The vector product is anti-commutative because changing the order of the vectors changes the direction of the vector product by the right hand rule: →A × →B = − →B × →A. The vector product between a vector c→A where c is a scalar and a vector →B is c→A × →B = c(→A × →B) Similarly, →A × c→B = c(→A × →B). This is called a moment of force or torque. The cross product between 2 vectors, in this case radial vector cross with force vector, results in a third vector that is perpendicular to both the radial and the force vectors. Depending on which hand rule you use, the resulting torque could be into or out of the page. Comment.
