A
proton with speed v = 4.7x106 m/s in the x-y plane and mass mp =
1.67x10-27 kg is injected into a uniform magnetic field region that
points in the positive z-direction. The proton also has a component
of velocity 1.1 × 106 m/s along the B field direction. The magnetic
field intensity is B = 0.35 T. (a) (25 points) Draw a good physics
diagram. Use appropriate perspective(s) for your diagram. (b) (50
points) Find the radius of the orbit. (c) (25 points) Find the
period of the orbit.
