vector

Vector Product:

If we multiply a vector with any other vector or scalar quantity then the result is called vector product.

Multiplying a vector by a scalar:

If we multiply a vector \overrightarrow{a} by a scalar K , then the result is a new vector.
The magnitude of the vector formed by multiplying \overrightarrow{a} and K , is the magnitude of \overrightarrow{a} multiplied by K and the direction of the vector is same as vector \overrightarrow{a} if K is positive and exactly opposite of K is negative.
And to divide the vector \overrightarrow{a} with K we can simply multiply the vector \overrightarrow{a} with \frac{1}{k}.
