Application +4 | -1

\vec A = \hat i + \hat j + \hat k

and

\vec B = 2\hat i - \hat j + 4\hat k

then the unit vector along

\vec A + \vec B

View answer and explanation

Correct option: C

\frac{{3\hat i + 5\hat k}}{{\sqrt {34} }}

Option C (

\frac{{3\hat i + 5\hat k}}{{\sqrt {34} }}

) is correct because it's the unit vector in the direction of the sum of the two vectors.
