Answer:
The vector or cross product is another way to combine two vectors; it creates a vector perpendicular to both it the originals.In vector form, torque is the cross product of the radius vector (from axis of rotation to point of application of force) and the force vector.Viewgraph 3

There are other ways of computing and expressing the cross product of two vectors. For example, given two vectors A and B in the standard unit-vector notation
one can combine the components of the two vectors to form the cross product A x B like so:
