Let , , be three non-zero vectors such that no two of these are collinear. If the vector + 2 is collinear with , then + 2 + 6 equals
λ (λ ≠ 0, a scalar)
0
If vectors from a triangle, then it is
equilateral
isosceles
right-angled
obtuse-angled
The component of a vector is
always less than its magnitude
always greater than its magnitude
always equal to its magnitude

A vector whose magnitude is of unit length is called
zero vector
unit vector
position vector
collinear vector
