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

π
π/4
π/2
The summation of two unit vectors is a third unit vector, then the modulus of the difference of the unit vectors is
If G is the centroid of the , then is equal to
