Cyclotron — UPSC Physics Optional CSE 2020 Paper I

In a certain cyclotron, the maximum radius that the path of a deuteron may have before it is deflected out of the magnetic field is 20\,\mathrm{cm}.

(i) Calculate the velocity of the deuteron at this radius.

(ii) What is the energy of deuteron in \mathrm{MeV}? Given, magnetic field =1500 gauss and mass of deuteron =3.34\times10^{-27}\,\mathrm{kg}.
