If are the position vectors of the vertices of an equilateral triangle, whose ortho centre is at the origin, then
If is a vector of magnitude 21 and has direction ratios 2,-3,6, then value of is
If , then the value of is
If m1, m2, m3, and m4 are respectively the magnitudes of the vectors , then the correct order of m1, m2, m3, and m4 is
m3 < m1 < m4 < m2
m3 < m1 < m2 < m4
m3 < m4 < m1 < m2
m3 < m4 < m2 < m1
Two vectors when act along the same line or along parallel lines are called
Collinear vectors
Coplanar vectors
Equal vectors
Position vectors
If G is the centroid of the , then is equal to
The perimeter of the triangle whose vertices have the position 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
Two vectors and are equal if
their magnitudes are equal
they originate from the same point
their direction is same
their magnitude as well as direction is same
Let ABC be a triangle, the position vectors of whose vertices are respectively . Then, the is
isosceles
equilateral
right angled isosceles
