Vector a points north east and its magnitude is 3 kg metre per second

1.	Vector a points north east and its magnitude is 3 kg metre per second it is multiplied by the scalar alphastar that alpha equals to minus 4 seconds find the direction and magnitude of the new vector quantity does it represent the same physical quantity or not
Answer» Explanation: Here in this CASE *DIRECTION becomes OPPOSITE. So the vector is directed SOUTH west.* *Direction becomes opposite. So the vector is directed South west. A physical quantity REMAINS the same physical quantity when multiplied by a scalar.*

Answer»

Explanation:

Here in this CASE DIRECTION becomes OPPOSITE. So the vector is directed SOUTH west.

Direction becomes opposite. So the vector is directed South west. A physical quantity REMAINS the same physical quantity when multiplied by a scalar.
