Motion In A Plane

Question

If the coordinates of points P and Q are (3, 1, -2) and (1, -2, 2) respectively, then find the vector $PQ with rightwards arrow on top ?$

Solution

The vector PQ is [(3-1) $straight i with hat on top$ + (1-(-2) $straight j with hat on top$ + (-2-2) $straight k with hat on top$
So,
$PQ with rightwards arrow on top space equals space minus 2 straight i with hat on top minus 3 straight j with hat on top plus 4 straight k with hat on top.$
