rA proton, a deutron and an α- particle having the same kinetic energy are moving in circular trajectories in
a constant magnetic field. If rp, rd and rα denote respectively the radii of the trajectories of these particles,
then
(a) rα ˃ rd ˃ rp (b) rα= rp˂ rd `` (c) rα= rd ˃ rd (d) rα= rd = rd

Answer:
Explanation:
the formula of radii is r=MV/BQ
the masses is mp=m, md=2m, mα=4m
the charges is Qp=+q, Qd=+q, Qα=+2q
rp=mv/bq
rd=2mv/bq
rα=4m/b2q=2m/bq
rd=rα>rp
