Question
In Fig 10.6 (a square), identify the following vectors.
Collinear but not equal.
Collinear but not equal.
✓
Answer
$\vec{a}\ \text{and}\ \vec{c}$ have parallel support, so that they are collinear. Since they have opposite directions, they are not equal. Hence $\vec{a}\ \text{and}\ \vec{c}$ are collinear but not equal.
