What is the condition under which the magnitude of cross product is equal to the dot product ?

Explanation

To determine the condition under which the magnitude of the cross product of two vectors is equal to the dot product of the same two vectors, we can follow these steps:

### Step-by-Step Solution:

1. **Define the Vectors**: Let the two vectors be \( \vec{A} \) and \( \vec{B} \).

2. **Write the Formulas**:
- The magnitude of the cross product \( |\vec{A} \times \vec{B}| \) is given by:
