In a nuclear experiment a proton with kinetic energy 3.5 MeV moves in a circular path in a uniform magnetic field. a)If the magnetic field is B = 1.1 T what is the radius of the orbit? b) What energy must an alpha particle (q = +2e, m = 4.0 u) and a deuteron (q = +e, m = 2.0 u) have if they are to circulate in the same orbit? Energy of the alpha? (MeV) c)Energy of the deuteron?
