A cyclotron’s oscillator frequency is 10 MHz. What should be the operating magnetic field for accelerating protons, if the radius of its dees is 60 cm ? What is the kinetic energy of the proton beam produced by the accelerator? Given `e = 1.6 xx 10^(–19) C, m = 1.67 xx 10^(–27)` kg. Express your answer in units of MeV `[1MeV = 1.6 xx 10^(–13) J]`.
