A) Collinear
B) Non-collinear
C) Form a right angled triangle
D) None of these
Correct Answer: A
Solution :
Here \[\overrightarrow{AB}=\mathbf{b}-\mathbf{a}\] and \[\overrightarrow{AC}=(3\mathbf{a}-2\mathbf{b})-(\mathbf{a})=-2(\mathbf{b}-\mathbf{a})\] Therefore, it is of the form \[\overrightarrow{AB}=m\overrightarrow{AC}.\] Hence A, B, C are collinear.You need to login to perform this action.
