Two non zero vectors `vecA "and" vecB` are such that `|vecA+vecB|=|vecA - vecB|`. Find angle between `vecA "and " vecB`?

Explanation

To find the angle between two non-zero vectors \(\vec{A}\) and \(\vec{B}\) given that \(|\vec{A} + \vec{B}| = |\vec{A} - \vec{B}|\), we can follow these steps:

### Step-by-Step Solution:

1. **Start with the given equation**:
\[ |\vec{A} + \vec{B}| = |\vec{A} - \vec{B}| \]
