Let the position vectors of two points P and Q be 3\widehat i - \widehat j + 2\widehat k and \widehat i + 2\widehat j - 4\widehat k, respectively. Let R and S be two points such that the direction ratios of lines PR and QS are (4, -1, 2) and (-2, 1, -2), respectively. Let lines PR and QS intersec... | Watch the step-by-step video solution for this NIMCET PYQ.
