Given vectors are coplanar.
Let and , are non - zero and non- collinear vectors. If there exists scalars α, β such that α + β = , then
α = β ≠ 0
α + β = 0
α = β = 0

If C is the midpoint of AB and P is any point outside AB, then
ABCD is a quadrilateral, P,Q are the midpoints of and , then is equal to
The position vectors of P and Q are respectively and . If R is a point on such that , then the position vector of R is
