A vector joining two points is found by applying the:
AChain rule s
BTriangle law
CQuotient law
DProduct rule
Answer & Solution
Correct answer: B. Triangle law
1. Join both points to the origin first.
2. The three vectors then form a triangle.
3. Applying the triangle law gives the joining vector.
4. So the answer is the triangle law.
