Question

Give an example for multiplication of a vector by a scalar.​

Answer 1

Answer:

Product of vector with scalar - example

The product of a scalar with vector is always a vector. Example: The product of mass 'm' and acceleration a gives rise to a vector quantity 'force'. The product of mass 'm' and velocity v gives rise to a vector quantity 'momentum'.

Answer 2

Suppose we have a vector \overrightarrow {a} , then if this vector is multiplied by a scalar quantity k then we get a new vector with magnitude as | \overrightarrow {ka} |and the direction remains same as the vector \overrightarrow {a} if k is positive and if k is negative then the direction of k becomes just opposite..
