If C is the midpoint of AB and P is any point outside AB, then
The resultant of
√29
√66
4
√62 - 2 √35
If then the unit vector in the direction of is.
ABCD is a quadrilateral, P,Q are the midpoints of and , then is equal to
If , , are three vectors such that = + and the angle between and is π/2, then
a2 = b2 + c2
b2 = c2 + a2
c2 = a2 + b2
2a2 - b2 = c2
A, B C, D, E, F in that order, are the vertices of a regular hexagon with centre origin. If the position vectors of the vertices A and B are respectively. is equal to
If and are vectors such that , then the angle between and is
120o
60o
90o
30o
If then angle between and is
π/6
π/3
π/2
π
If the position vector of A with respect to O is then the position vector of B with respect to 0 is
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
α = β
