1) A plot of binding energy per nucleon Eb
A versus the mass number (A) shows that nuclei with a small mass number have a small binding energy per nucleon, as the mass number increases the binding energy per nucleon increases, and the value for the binding energy per nucleon has a maximum value for nuclei with a mass number around 60. Verify that this is the case by determining the binding energy per nucleon for each of the following four nuclei. (Let the mass of a proton be 1.0078 u, the mass of a neutron be 1.0087 u, the mass of 6He be 6.0189 u, the mass of 7Li be 7.0160 u, the mass of 62Co be 61.9341 u, and the mass of 107Ag be 106.9051 u. Enter your answers in MeV and to at least three significant figures.)
2.Determine the minimum energy (in MeV) needed to remove just one proton from the nucleus 126C. (Let the mass of a proton be 1.0078 u, the mass of 126C be 12.0000 u, and the mass of 115B be 11.0093 u.)
3.Given that the energy needed to assemble a uniformly charged sphere of radius R and charge Q is U = 3keQ2/5R,
where ke is the Coulomb constant, determine the energy (in MeV) needed to overcome the Coulomb repulsion of 18 protons uniformly distributed throughout a sphere the size of an Ar-40 nucleus.
