A cyclotron is used to accelerate protons. If the operating magnetic field is 1.0 T and the radius of the cyclotron 'dees' is 60 cm, the kinetic energy of the accelerated protons in MeV will be :

$\text{ [use }{\mathrm{m}}_{\mathrm{p}}=1.6\times {10}^{-27}\mathrm{kg}, \mathrm{e}=1.6\times {10}^{-19}\mathrm{C}\text{ ] }$
