Properties of Scalar Product:-
(i) Scalar product is commutative, i.e., A * B= B*A
(ii) Scalar product is distributive, i.e., A * (B + C) = A * B + A * C
(iii) Scalar product of two perpendicular vectors is zero. A * B = AB cos 90°=O
(iv) Scalar product of two parallel vectors is equal to the product of their magnitudes, i.e., A * B = AB cos 0° = AB
(v) Scalar product of a vector with itself is equal to the square of its magnitude, i.e.,
A * A = AA cos 0° = A2
