Q89.If the lines xโk k is _______. 1 = 2 = zโ33 and x+13 = y+22 = z+31 are co-planar, then the value of
What This Question Tests
This question tests the knowledge of the condition for two lines in 3D to be coplanar, requiring the formation and evaluation of a determinant involving the coordinates of points on the lines and their direction ratios.
Concepts Tested
Formulas Used
Condition for coplanarity of lines (x-x1)/a1 = (y-y1)/b1 = (z-z1)/c1 and (x-x2)/a2 = (y-y2)/b2 = (z-z2)/c2: |(x2-x1) (y2-y1) (z2-z1)| / |a1 b1 c1| / |a2 b2 c2| = 0
