c the R energy the momentum d None of these proton moves at a speed v 2x10 in a region of constant magnetic field of magnitude B 0 05 T The direction of the proton when it enters this field is 0 30 to the field When you look along the direction of the magnetic field 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 201 a 4 35 m c 2 82 m b 0 209 m d 2 41 m a b 39
