The summation of two unit vectors is a third unit vector, then the modulus of the difference of the unit vectors is
If is a vector of magnitude 21 and has direction ratios 2,-3,6, then value of is
ABCDEF is a regular hexagon with center at the origin such that . Then λ is equal to
2
4
6
8
If 0 is the origin and op = 3 with direction ratios are -1,2,-2, then co-ordinates of point p are
(-1,2,-2)
(1,2,2)
(3,6,-9)
The non-zero vectors , and are related by = 8 and = -7. Then, the angle between and is

0
π/4
π/2
If are adjacent sides of a parallelogram, then the lengths of its diagonals are
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, , then is equal to
Two vectors when act along the same line or along parallel lines are called
Collinear vectors
Coplanar vectors
Equal vectors
Position vectors
If position vectors of A and B are , then magnitude of is
32
24
20
14
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)
