Question

Disguise between scalar product and vector product of two vector

Answer 1

Vectors can be multiplied in two different ways: the scalar and vector product. As the name says, a scalar product of two vectors results in a scalar quantity, and a vector product in a vector quantity.

1. Scalar Product

The result of this product is a scalar quantity. The scalar product between two vector is denoted by a thick dot:

If  is perpendicular to , the scalar product vanishes.

2. Vector Product

The result of this product is a vector quantity. The vector product between two vector is denoted by a cross (the product is sometimes also called "cross-product"):

✔️Scalar Product:

• The magnitude of scalar product is equal to the product of the magnitudes of the two vectors and the cosine of the angle between them.

• It has no direction.

• It obeys the commutative law of vector multiplication.

• It is Zero if the two vectors are mutually perpendicular to each other.

• The self dot-product of a vector is equal to the square of it's magnitude.

✔️Vector Product:

• The magnitude of vector product is equal to the product of the magnitude of the two vectors and sine of small angle (∅) between them.

• It's direction is perpendicular to the plane of the vectors.

• It doesn't obey the commutative law of vector multiplication.

• It is Zero if the two vectors are parallel or antiparallel to each other.

• The self cross-product of a vector is zero.
