The vector that must be added to \stackrel{\^}{\bo {i}}-3 \stackrel{\^}{\bo {j}}+2 \stackrel{\^}{\bo {k}} and 3 \stackrel{\^}{\bo {i}}+6 \stackrel{\^}{\bo {j}}-7 \stackrel{\^}{\bo {k}} so resultant vector is a unit vector along the X - axis is

Correct Answer is : −3^i−3^j+5^k

4 \stackrel{\^}{\bo {i}}+2 \stackrel{\^}{\bo {j}}+5 \stackrel{\^}{\bo {k}}

-3 \stackrel{\^}{\bo {i}}-3 \stackrel{\^}{\bo {j}}+5 \stackrel{\^}{\bo {k}}

3 \stackrel{\^}{\bo {i}}+4 \stackrel{\^}{\bo {j}}+5 \stackrel{\^}{\bo {k}}
