Two vectors when act along the same line or along parallel lines are called
Collinear vectors
Coplanar vectors
Equal vectors
Position vectors
If A B C D E F is regular hexagon, then the value of is
0

If 0 is the origin and = 3 with direction ratios are -1,2,-2, then co-ordinates of point p are
(-1,2,-2)
(1,2,2)
(3,6,-9)
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
If vectors from a triangle, then it is
equilateral
isosceles
right-angled
obtuse-angled
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
A vector whose magnitude is of unit length is called
zero vector
unit vector
position vector
collinear vector
Direction of zero vector
does not exist
is towards origin
is indeterminate
None of these
If is a vector of magnitude 21 and has direction ratios 2,-3,6, then value of is
