A deuteron in a large cyclotron in a magnetic field with B = 1.5 T and a radius of passage of 2.0 m. Due to a grazing collision with a target, the deuteron breaks apart, with a negligible loss of kinetic energy, into a proton and a neutron. Assume that the energy of the deuteron is shared equally by the protons and neutrons when the deuteron breaks apart. Determine the motion of the protons and neutrons respectively.
