Question

If a particle moves from point P(2,3,5) to point Q(3,4,5). Its displacement vector be (A)  hati+ hatj+10 hatk (B)  hati+ hatj+5 hatk (C)  hati+ hatj (D) 2 hati+4 hatj+6 hatk

Displacement vector vecr=Δ x hati+Δ y hatj+Δ z hatk =(3-2) hati+(4-3) hatj+(5-5) hatk= hati+ hatj

Q. If a particle moves from point $P (2, 3, 5)$ to point $Q (3, 4, 5)$ . Its displacement vector be

$\hat{i} + \hat{j} + 10 \hat{k}$

$\hat{i} + \hat{j} + 5 \hat{k}$

$\hat{i} + \hat{j}$

$2 \hat{i} + 4 \hat{j} + 6 \hat{k}$

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