An alpha particle with kinetic energy 13.5 MeV makes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude L= p 0 b , where p 0 is the magnitude of the initial momentum of the alpha particle and b =1.10×10−12 m . (Assume that the lead nucleus remains stationary and that it may be treated as a point charge. The atomic number of lead is 82. The alpha particle is a helium nucleus, with atomic number 2.) Part A What is the distance of closest approach? r r = nothing m SubmitRequest Answer Part B Repeat for b =1.00×10−13 m . r r = nothing m SubmitRequest Answer Part C Repeat for b =1.50×10−14 m .

If the alpha particles have an initial kinetic energy of 7.7 MeV, then assuming a head-collision between an alpha particle (helium nucleus with +2e charge) and a gold nucleus (79 protons, so +79e charge), and using conservation of energy at the point of closest approach when all of the alpha particle's kinetic energy is converted to electric potential energy, calculate the approximate distance of closest approach (and thus coarsely estimate the size of the nucleus)

An atomic nucleus initially moving at 390 m/s emits an alpha particle in the direction of its velocity, and the remaining nucleus slows to 250 m/s . Part A If the alpha particle has a mass of 4.0 u and the original nucleus has a mass of 222 u , what speed does the alpha particle have when it is emitted?
