In a cyclotron, the orbital radius of protons with energy 300 keV is 16.0 cm. You are redesigning the cyclotron to be used instead for alpha particles with energy 300 keV. An alpha particle has charge q = +2e and mass m = 6.64 * 10^-27 kg. If the magnetic field isn’t changed, what will be the orbital radius of the alpha particles?

In a cyclotron, the orbital radius of protons with energy
300 keV is 16.0 cm. You are redesigning the cyclotron to be used
instead for alpha particles with energy 300 keV. An alpha par-
ticle has charge q = +2e and mass m = 6.64 × 1027 kg. If the
magnetic field isn't changed, what will be the orbital radius of
the alpha particles?
