MCQ
If a particle moves from point $P(2,3,5)$ to point $Q(3,4,5)$. Its displacement vector be
- A$\hat{i}+\hat{j}+10 \hat{k}$
- B$\hat{i}+\hat{j}+5 \hat{k}$
- ✓$\hat{i}+\hat{j}$
- D$2 \hat{i}+4 \hat{j}+6 \hat{k}$
✓
Answer
Correct option: C.
$\hat{i}+\hat{j}$
(c) Displacement vector $\vec{r}=\Delta x \hat{i}+\Delta \hat{y j}+\Delta z \hat{k}$$=(3-2) \hat{i}+(4-3) \hat{j}+(5-5) \hat{k}=\hat{i}+\hat{j}$
