Find unit vector in the direction of vector ` -> a=2 hat i+3 hat j+ hat k`.

Explanation

To find the unit vector in the direction of the vector \( \vec{a} = 2 \hat{i} + 3 \hat{j} + \hat{k} \), we will follow these steps:

### Step 1: Identify the components of the vector
The vector \( \vec{a} \) has the following components:
- \( a_x = 2 \) (coefficient of \( \hat{i} \))
- \( a_y = 3 \) (coefficient of \( \hat{j} \))
- \( a_z = 1 \) (coefficient of \( \hat{k} \))
