Can the magnitude of `vecA -vecB` be equal to `vecA+vecB`?

Explanation

To determine whether the magnitude of \(\vec{A} - \vec{B}\) can be equal to \(\vec{A} + \vec{B}\), we can analyze the problem using the properties of vectors and their magnitudes.

### Step-by-Step Solution:

1. **Understanding the Magnitudes**:
We need to find out if:
\[
|\vec{A} - \vec{B}| = |\vec{A} + \vec{B}|
