Vedclass · Answer

(C) The displacement vector $\vec{d}$ is defined as the difference between the final position vector $\vec{r}_Q$ and the initial position vector $\vec{r}_P$.Given $P = (2, 3, 5)$ and $Q = (3, 4, 5)$.$\vec{r}_P = 2\hat{i} + 3\hat{j} + 5\hat{k}$$\vec{r}_Q = 3\hat{i} + 4\hat{j} + 5\hat{k}$Displacement vector $\vec{d} = \vec{r}_Q - \vec{r}_P = (3 - 2)\hat{i} + (4 - 3)\hat{j} + (5 - 5)\hat{k}$$\vec{d} = 1\hat{i} + 1\hat{j} + 0\hat{k} = \hat{i} + \hat{j}$.

If a particle moves from point $P (2, 3, 5)$ to point $Q (3, 4, 5)$,its displacement vector is:
