In vector multiplication, there are two types of multiplication: One in which the result is a scalar and the other in which the result is a vector.

Accordingly the two types of products of vectors are:

Scalar product (also called dot product) denoted by**A.B**

Vector product (also called cross product) denoted by **AxB**

**A.B ** = AB cos Θ, where Θ is the angle between the directions of **A** and **B**

The physical meaning of dot product is that, “*The product of the magnitude of one vector and the magnitude of the component of the other vector in the direction of the first vector*.”

**AxB **= AB sinΘ

The direction of cross product is given by right hand cork screw rule
