Marks: +1, -0
Find the value of λ\lambda for which the following lines are perpendicular to each other :
x−55λ+2=2−y5=1−z−1;x1=y+122λ=z−13\frac{x-5}{5\lambda+2} = \frac{2-y}{5} = \frac{1-z}{-1} ; \frac{x}{1} = \frac{y+\frac{1}{2}}{2\lambda} = \frac{z-1}{3}
Hence, find whether the lines intersect or not.
