In a Rutherford scattering experiment, when a projectile of charge \(Z_1\) and mass \(M_1\) approaches a target nucleus of charge \(Z_2\) and mass \(M_2\), the distance of the closest approach is \(r_0\). The energy of the projectile is:
| 1. | directly proportional to \(M_1M_2\). |
| 2. | directly proportional to \(Z_1Z_2\). |
| 3. | inversely proportional to \(Z_1\). |
| 4. | directly proportional to mass \(M_1\). |
