If the angle between unit vectors `veca and vecb is 60^(@)` . Then find the value of `|veca -vecb|`.

Explanation

To solve the problem of finding the value of \(|\vec{a} - \vec{b}|\) given that the angle between the unit vectors \(\vec{a}\) and \(\vec{b}\) is \(60^\circ\), we can follow these steps:

### Step 1: Understand the Properties of Unit Vectors
Since \(\vec{a}\) and \(\vec{b}\) are unit vectors, we know that:
\[ |\vec{a}| = 1 \quad \text{and} \quad |\vec{b}| = 1 \]
