Vedclass · Answer

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

$A$ particle moves from point $P (2, 3, 5)$ to point $Q (3, 4, 5)$. The displacement vector is:
