**CROSS PRODUCT OF TWO VECTORS**** **

In many situation the product of two vectors may yield vector-quantity. This type of product is cross product of vectors. The cross product of vectors A and B is given by C where C is a vector perpendicular to the plane containing A and B . The direction of C can be determined by right hand screw rule. The magnitude of C is given by

As per Fig. 2.10, we have

Distributive law is applicable for cross product

Cross Product of unit vectors
