A proton that has flown into a magnetic field moves in a circle making 10 ^ 8 revolutions in 1 s. With what frequency will the a-particle rotate in the same magnetic field?
Answer: 0.5 * 10 ^ 8Hz
Since the charge of alpha particles is twice as large as that of a proton, the mass is four times greater. The rotation frequency of particles in a magnetic field is proportional to the specific charge. From this we conclude that the frequency is two times less.
