Question
If a scalar is multiplied by a vector, the whole quantity becomes?
- Scalar
- Vector
- Tensor
- None of the above
Hint:
Vector
The correct answer is: Vector
If the scaler is multiplied by a vector, the whole quantity becomes vector.
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.
