Vedclass · Answer

(B) The position vector $\vec{r}$ of a point $P(x, y, z)$ in a three-dimensional Cartesian coordinate system is given by the formula: $\vec{r} = x\hat{i} + y\hat{j} + z\hat{k}$.Given the coordinates of the particle are $(3, 2, 5)$,where $x = 3$,$y = 2$,and $z = 5$.Substituting these values into the formula,we get the position vector: $\vec{r} = 3\hat{i} + 2\hat{j} + 5\hat{k}$.Therefore,the correct option is $B$.

The position of a particle in a rectangular coordinate system is $(3, 2, 5)$. Then its position vector will be
