Is it possible that the scalar product of two vectors is negative ?

Explanation

To determine if the scalar product (or dot product) of two vectors can be negative, we can follow these steps:

### Step 1: Understand the Definition of Scalar Product
The scalar product (or dot product) of two vectors **A** and **B** is given by the formula:
\[ \mathbf{A} \cdot \mathbf{B} = |\mathbf{A}| |\mathbf{B}| \cos \theta \]
where:
- \( |\mathbf{A}| \) is the magnitude of vector **A**,
- \( |\mathbf{B}| \) is the magnitude of vector **B**,
