A proton enters a uniform magnetic field (into the page of 7500nT with a speed of 0.91 Gm/s. (a) At what angle must the velocity be from the magnetic field so that the pitch of the resulting helical motion is equal to the radius of the helix? (b) What is the length of the helix after a million complete revolutions? (tip: imagine a triangle wrapped around a cylinder) (d) How long did the proton take to complete a million revolutions?
