What should be the effect of impact parameter upon the deviation of `alpha`-particle.

Explanation

To analyze the effect of the impact parameter on the deviation of an alpha particle during its interaction with an atomic nucleus, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Impact Parameter**:
- The impact parameter (b) is defined as the perpendicular distance from the center of the nucleus to the path of the incoming alpha particle. It represents how close the alpha particle comes to the nucleus during its trajectory.

2. **Coulomb's Force**:
