A proton moves at a speed v = 2xx10^(6) m//s in a region of constant magnetic field of magnitude B = 0.05 T. The direction of the proton when it enters this field is theta = 30^(@) to the field. When you look along the direction of the magnetic field, then the path is a circle projected on a plane perpendicular to the magnetic field. How far will the proton move along the direction of B when two projected circles have been completed?
