Find the angle between two vectors ` veca`and ` vecb`with magnitudes `sqrt(3)`and 2 respectively having ` veca cdot vecb=sqrt(6)`

Explanation

To find the angle between two vectors \( \vec{a} \) and \( \vec{b} \) with given magnitudes and dot product, we can use the formula for the dot product of two vectors:

\[ \vec{a} \cdot \vec{b} = |\vec{a}| |\vec{b}| \cos \theta \]

### Step 1: Identify the given values
- Magnitude of \( \vec{a} \): \( |\vec{a}| = \sqrt{3} \)
