(8c28p20) In a nuclear experiment a proton with kinetic energy 3.5 MeV moves in a circular path in a uniform magnetic field. If the magnetic eld is B = 2.2 Twhat is the radius of the orbit? 1.23x10'1 m You are correct. Your receipt no. is 155-3849 (0) W 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) 3.50 Mev YOU are correct. Your receipt no. is 155-5043 6}) w Energy of the deuteron? 172 meV Submit Answer Incorrect. Tries 1/4 Previous Tries
