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
Direction of zero vector
does not exist
is towards origin
is indeterminate
None of these
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
