Question

Can scaler product of two vectors be negative? provide proof and examples​

Answer 1

Answer:

Yes. The scalar product can be thought of as a projection of one vector onto another. If they are facing in different directions, that is, if the angle between them is more than 90 degrees, this projection will be negative.

Answer 2

Answer:

Yes

Explanation:

Scalar product will be negative if θ>90∘. ∵→P⋅→Q=PQcosθ ∴ When θ>90∘ then cosθ is negative and →P⋅→Q will be negative.
