The perimeter of the triangle whose vertices have the position vectors is
Two vectors when act along the same line or along parallel lines are called
Collinear vectors
Coplanar vectors
Equal vectors
Position vectors
The summation of two unit vectors is a third unit vector, then the modulus of the difference of the unit vectors is
The component of a vector is
always less than its magnitude
always greater than its magnitude
always equal to its magnitude
None of these
If and are the position vectors of A and B, then position vector of a point C on AB produced such that AC = 3 AB is
Let ABC be a triangle, the position vectors of whose vertices are respectively . Then, the is
isosceles
equilateral
right angled isosceles
If , then the unit vector in the direction of is
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
