Description: The position vectors of the vertices A,B,C of a triangle are 2\hat i-3\hat j+3\hat k, 2\hat i+2\hat j+3\hat k and -\hat i+\hat j+3\hat k respectively. Let l denote the length of the angle bisector AD of \angle BAC (where D is on the line segment BC). Then 2l^2 equals: | Watch the step-by-step video solution for this NIMCET PYQ.
