If the line with direction ratios 2, -1, 2 is perpendicular to the line with direction ratios 1, k, -3, then k =

If the line with direction ratios 5, 3k, 7 is perpendicular to the line with direction ratios k, 1, -8, then k =

If the cosine of the angle between the lines with direction ratios 1, -1, 2 and 0, 1, k is (sqrt(3))/(2) , then k =

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

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

Determine the value of k so that the line joining points A(k,1,-1) and B(2,0,2k) is perpendicular to the line joining the points C(4,2k,1) and D(2,3,2) .
