Answer :

Final answer:

Multiplying a vector by a negative scalar changes its magnitude and direction oppositely.


Explanation:

When a vector is multiplied by a scalar, if the scalar is negative, it changes the vector's magnitude and direction oppositely. For example, multiplying a vector by -2 results in the magnitude doubling while changing the direction.

Multiplying a vector by a scalar involves multiplying each component of the vector individually by that quantity. This process also affects the magnitude of the vector accordingly.

Key takeaway: Multiplying a vector by a negative scalar alters both magnitude and direction oppositely.
