A cyclotron is used to accelerate protons. If the operating magnetic field is 1.0 \mathrm{~T} and the radius of the cyclotron 'dees' is 60 \mathrm{~cm}, the kinetic energy of the accelerated protons in MeV will be :
[\mathrm{use} \,\,\mathrm{m}_{\mathrm{p}}=1.6 \times 10^{-27} \mathrm{~kg}, \mathrm{e}=1.6 \times 10^{-19} \,\mathrm{C} ]
