COLLINEAR VECTORS-
2 points are said to be colinear if they lie on the same line. ---A---->----B---> Here in this diagram,
points A and B lie on the same line and hence are colinear. Thus when 2 vectors act along the same line, then they are said to be colinear.
Colinear Vectors are also Parallel vectors except that they lie on the same line.
If 2 vectors are collinear , say 'a' and 'b' then if a = k*b they are collinear ....
COPLANER VECTORS -
2 vectors are said to be Co planar if they act in the same plane but they have diferent/same magnitudes and phases....
Mathematically => when 2 vectors are collinear, the dot product of the vectors are 1 and their cross product is zero.(As angle between them is zero)
approve if u like my ans
