Question

null vector dot A vector??​

Answer 1

Explanation:

The dot product of two vectors let us say A⃗ and B⃗ is defined as

A⃗ ⋅B⃗ ≡ABcosθ,

where A and B are the magnitudes of the vectors A⃗ and B⃗ respectively. The dot product, in its definition, not only includes the magnitudes of the vectors, but also the angle between them.
