If the magniude of two vectors are `6 N` and 3 N` and magnitude of their dit product is `9 N` theb find the angle between the two vectors.

Explanation

To find the angle between the two vectors given their magnitudes and the magnitude of their dot product, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Magnitude of vector A, |A| = 6 N
- Magnitude of vector B, |B| = 3 N
- Magnitude of the dot product, A · B = 9 N
