If an alpha nucleus of energy bombards a heavy nuclear target of charge Ze, then the distance of closest approach for the alpha nucleus will be proportional to:
1. | \(\frac{1}{Ze} \) | 2. | \(v^2 \) |
3. | \(\frac{1}{m} \) | 4. | \(\frac{1}{v^4}\) |
If the nucleus has a nuclear radius of about 3.6 fermis, then would have its radius approximately as:
1. 6.0 Fermi
2. 9.6 Fermi
3. 12.0 Fermi
4. 4.8 Fermi
The radius of Germanium (Ge) nuclide is measured to be twice the radius of . The number of nucleons in Ge is:
1. 73
2. 74
3. 75
4. 72
