If cross product of two non - zero vectors is zero, then the vectors are
Collinear
Co - directional
Co - initial
Co - terminus
1
6
0
3
-40
40
40 or -40
None of these
If two vectors be such that , then the angle between them is
π/4
π/3
π/2
The vectors
Coincident
Parallel
Perpendicular
Neither parallel nor perpendicular
Two vectors are parallel and have same magnitude.Then
They have the same direction
They are equal
They are not equal
They may or may not be equal
Let the vectors
A unit vector
