You have been able to get a part-time job in a University study the forces between nuclei in order to understand the energy output of the Sun. To do this experiment, you shoot alpha particles from a Van de Graaf accelerator at a sheet of lead. The alpha particle is the nucleus of a helium atom and laboratory. The group is planning a set of experiments to is made of 2 protons and 2 neutrons. The lead nucleus is made of 82 protons and 125 neutrons. The mass of the neutron is almost the same as the mass of a proton. To assure that you are actually studying the effects of the nuclear force, an alpha particle should come into contact with a lead nucleus. Assume that both the alpha particle and the lead nucleus have the shape of a sphere. The alpha particle has a radius of 1.0 x 10 1 cm and the lead nucleus has a radius 4 times larger. Your boss wants you to make two calculations: the lead nucleus is fixed at rest? the Van de Graaf accelerator if the alpha gas)? (a) What is the minimum speed of such an alpha particle if (b) What is the potential difference between the two ends of particle starts from rest at one end (from a bottle of helium
