If the straight lines `x=-1+s ,y=3-lambdas ,z=1+lambdasa n dx=t/2,y=1+t ,z=2-t ,` with paramerters `sa n dt ,` respectivley, are coplanar, then find `lambdadot`

If the straight lines x=1+s,y=-3-lambda s,z=1+lambdas and x=(1)/(2),y=1+t,z=2-t ,with parameters s and t respectively,are co-planar then lambda .Equals

If the straighat lines x=1+s,y=-3-lamdas,z=1+lamdas and x=t/2,y=1+t,z=2-t with parameters s and t respectively, are coplanar, then lamda equals (A) -1/2 (B) -1 (C) -2 (D) 0

If the lines x = 1 + s, y = - 3 - lamda s , z = 1 + lamda s and x = ( t ) / ( s ) , y = 1 + t , z = 2 - t are coplanar, then lamda is equal to

The distance between the lines x=1-4t, y=2+t, z=3+2t" and "x=1+s, y=4-2s, z=-1+s is

If the lines (x-1)/(-3) =(y-2)/(2lambda) =(z-3)/(2) " and " (x-1)/(3lambda) =(y-1)/(1)=(6-z)/(5) are perpendicular to each other then find the value of lambda
