Consider the line L_1 : {x+1}/3 = {y+2}/1 = {z+1}/2 L_2 : {x-2}/1 = {y+2}/2 = {z-3}/3 The unit vector perpendicular to both L_1 and L_2 is [JEE Adv 2008 P2]

Correct Answer is : −^i−7^j+5^k5√3

{-i^{\^}+7j^{\^}+7k^{\^}}/\sqrt{99}

{-i^{\^}-7j^{\^}+5k^{\^}}/{5\sqrt3}

{-i^{\^}+7j^{\^}+5k^{\^}}/{5\sqrt3}

{7i^{\^}-7j^{\^}-k^{\^}}/\sqrt{99}
