For the vectors `vecA and vecB` in the above example , find unit vector parallel to the resultant of the two vectors

Explanation

To find the unit vector parallel to the resultant of two vectors \(\vec{A}\) and \(\vec{B}\), we will follow these steps:

### Step 1: Find the Resultant Vector
The resultant vector \(\vec{R}\) is given by the sum of the two vectors:
\[ \vec{R} = \vec{A} + \vec{B} \]
Assuming \(\vec{A} = \hat{i} + 2\hat{j} - \hat{k}\) and \(\vec{B} = 2\hat{i} + 3\hat{j} + 2\hat{k}\), we can calculate \(\vec{R}\).
