Answer» ANSWER: A 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»

A 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
