Let O be the origin and the position vector of the point P be - \widehat i - 2\widehat j + 3\widehat k. If the position vectors of the points A, B and C are - 2\widehat i + \widehat j - 3\widehat k,2\widehat i + 4\widehat j - 2\widehat k and - 4\widehat i + 2\widehat j - \widehat k respectivel... | Watch the step-by-step video solution for this NIMCET PYQ.
