Answer
It is vector which denotes the position of a particle at any instant of time, with respect to some reference frame or coordinate system. The position $\vec{r}$ vector of the particle at a point $P$ is given by $ \overrightarrow{ r }= x \hat{i}+ y \hat{j}+ z \hat{k} $ where $x , y$ and $z$ are components of $\overrightarrow{ r }$.
