Question

the dot product of two non zero vectors​

Answer 1

Answer:

The dot product of a vector with the zero vector is zero. Two nonzero vectors are perpendicular, or orthogonal, if and only if their dot product is equal to zero.

Answer 2

Answer:

the dot product of two non zero vectors is zero

the dot product of the two vectors of non-zero magnitude is zero then

Explanation:

Dot product of two vectors a and b is

a

.

b

=abcosθ where θ is the angle between them.

abcosθ=0

⇒cosθ=0

⇒θ=90

they must be perpendicular
