dear ragha

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)
