To solve the problem of calculating the impact parameter for an alpha particle scattered by a gold nucleus, we can follow these steps:
### Step 1: Understand the Given Data
- Energy of the alpha particle (E) = 4 MeV
- Scattering angle (θ) = 20 degrees
- Atomic number of gold (Z) = 79
### Step 2: Convert Energy from MeV to Joules
