Question#10 Cyclotrons are widely used in nudeor medicine for producing short lived radioactive isotopes. There cyclotrons typically accelerate I" (the hydride ion, which has one proton and two elections) to an energy of S MeV to 20 MeV. This lon has a mass very close to that of a proton because the electron mass is negligible - about mer of the proton s mass. A typical magnetic field in such cyclotrons is 10 T. Part A What is the speed of a 5 0-MeV HIT Express your answer with the appropriate units ANSWER If the He has energy 5.0 MeV and B - 1.9 T. what is the radius of this lon's circular orbit Express your answer with the appropriate units
