The cross product of the free vectors a and b is the free vector a × b constructed as follows: • The direction of a × b is orthogonal to the plane determined by vectors and a and b; • Its magnitude, equal to a × b is given by the formula a×b = a b sin ϕ, a, b noncollinear 0, a, b collinear. 2 Operations with Free Vectors 17 • Its sense is given by the right-hand rule: if the vector a × b is grasped in the right hand and the fingers curl around from a to b through the angle ϕ, the thumb points in the direction of a × b (Fig.
