Find the value of `lamda` so that the lines `(1-x)/(3)=(7y-14)/(2lamda)=(z-3)/(2)` and `(7-7x)/(3lamda)=(y-5)/(1)=(6-z)/(5) ` are at right angles.

Find the value of lamda so that the straight lines: (1-x)/(3)= (7y -14)/(2 lamda)= (z-3)/(2) and (7-7x)/(3 lamda)= (y-5)/(1)= (6-z)/(5) are at right angles.

Find the value of 'lambda' so the lines: (1-x)/(3) = (7y -14)/(lambda) = (z-3)/(2) and (7 - 7x)/(3 lambda) = (y -5)/(1 ) = (6 - z)/(5) are at right angles. Also, find whether the lines are ntersecting or not .

Fiind m, if the lines (1-x)/(3)= ( 7y-14)/(2m ) = (z-3) /(2) and ( 7-7x)/(3m) = (y-5)/(1) = (6-z)/(5) are at right angles.
