Question
The angle between the vectors is _______ if they are orthogonal
- 90
- 65
- 30
- 45
Hint:
90°
The correct answer is: 90
The angle between the vectors is 90° if they are orthogonal.
Two vectors are orthogonal when they are perpendicular to each other. i.e. 90 degrees and the dot product of the two vectors is 0.

If a scalar is multiplied by a vector, the whole quantity becomes?
When a vector is multiplied by a scaler quantity, the magnitude of the vector quantity changes in accordance with the magnitude of the scaler quantity but the direction of the vector remains unchanged, hence, after multiplication of both the quantities the whole quantity becomes a vector quantity.
