Question

(A) The position vector of point $A$ is $\vec{r}_A = 2 \hat{i} + 2 \hat{j} + 3 \hat{k}$.The position vector of point $B$ is $\vec{r}_B = 6 \hat{i} + 6

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

Vedclass · Answer

(A) The position vector of point $A$ is $\vec{r}_A = 2 \hat{i} + 2 \hat{j} + 3 \hat{k}$.The position vector of point $B$ is $\vec{r}_B = 6 \hat{i} + 6 \hat{j} + 9 \hat{k}$.The displacement vector $\vec{d}$ is given by the change in position: $\vec{d} = \vec{r}_B - \vec{r}_A$.$\vec{d} = (6 - 2) \hat{i} + (6 - 2) \hat{j} + (9 - 3) \hat{k}$.$\vec{d} = 4 \hat{i} + 4 \hat{j} + 6 \hat{k}$.
