Can we multiply a vector by a scalar?

Answer

On multiplying a vector by a scalar, we get another vector whose magnitude is equal to the modulus of scalar times the magnitude of vector. The direction of the resultant vector is either same or opposite as that of vector depending upon whether scalar is positive or negative, respectively.
