Question

) Properties of scalan poroduct of two vector​

Answer 1

The scalar product of two vectors a and b of magnitude |a| and |b| is given as |a||b| cos θ, where θ represents the angle between the vectors a and b taken in the direction of the vectors. In the case, where any of the vectors is zero, the angle θ is not defined and in such a scenario a.b is given as zero.
