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
(c) Displacement vector $\overrightarrow {r\,} = \Delta x\hat i + \Delta y\hat j + \Delta z\hat k$
(c) Displacement vector $\overrightarrow {r\,} = \Delta x\hat i + \Delta y\hat j + \Delta z\hat k$
$ = (3 - 2)\hat i + (4 - 3)\hat j + (5 - 5)\hat k$$ = \hat i + \hat j$
