The vector having initial and terminal points as $(2, 5, 0)$ and $(-3, 7, 4)$, respectively is |
$-\hat{i} + 12\hat{j} + 4\hat{k}$ $5\hat{i} + 2\hat{j} - 4\hat{k}$ $-5\hat{i} + 2\hat{j} + 4\hat{k}$ $\hat{i} + \hat{j} + \hat{k}$ |
$-5\hat{i} + 2\hat{j} + 4\hat{k}$ |
The correct answer is Option (3) → $-5\hat{i} + 2\hat{j} + 4\hat{k}$ ## Required vector $= (-3 - 2)\hat{i} + (7 - 5)\hat{j} + (4 - 0)\hat{k}$ $[\text{Position vector} = \text{PV of terminal point} - \text{PV of initial point}]$ $= -5\hat{i} + 2\hat{j} + 4\hat{k}$ |
