Difference between scalar product ( dot product) and vector product.

Solution

Dot product or scalar product Cross product or vector product
If the product of two vectors is a scalar quantity, the product is called scalar product or dot product. If the product of two vectors is a vector quantity then the product is called vector product or cross product.
The dot product is defined by the relation:
A . B = AB Cos θ The cross product is defined by the relation:
A × B = AB Sinθ u
The scalar product obeys commutative law as
A.B =B.A The vector or cross product does not obey commutative law
A×B ≠B×A
If two vectors are perpendicular to each other then their scalar product is zero.
A.B =0 If two vectors are parallel to each other, their vector product is zero.
A×B=0
