Direction ratios of two lines are `3, -2, k` and `-2k, 4` Find k, if the lines are perpendicular to each other.

If direction ratios of two lines are 2,-6,-3 and 4,3,-1 then direction ratios of a line perpendicular to them are

If the direction cosines of a line are k, k and k, then :

If (1,-2,-2) and (0,2,1) are direction ratios of two lines, then direction cosines of a line perpendicular to both the lines are

If lines are perpendicular, then find the value of k.
