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