2 queations:
1) a proton enters a magnetic feild at a right angle to the field. an alpja particle enters the same field at the same angle but with twice the speed. once in the magnetic field both particles move in a circular path. the raito of radius of the alpha particles path to the radius of the protons path is?
[4:1]

2) a proton and an alpha particle have an identical circular orbits in a magnetic field. the proton has a speed of 4.4 m/s. the speed of the aplha particle is?
[2.2^5 m/s]

thank you
