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 byA.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

Shashi Kant asked:
“What is difference between cross product and dot product?”
If the product of two vectors is a scalar quantity it is called scalar product or dot product.
If the product of two vectors is a vector quantity it is called vector product or cross product.
