Question: A cyclotron for accelerating protons has a magnetic field of 1.4 T and a radius of 0.7 m.
(a) What is the cyclotron frequency?
(b) Find the maximum energy of the protons when they emerge.
(c) How will your answers change if deuterons, which have the same charge but twice the mass, are used instead of protons?
