A proton moving with a speed of 1.50 Ã 10 ^6 m/s enters a regioncontaining a uniform magnetic ?eld of magnitude 0.500 T pointing inthe -z direction. The velocity vector is at an angle of 60? withrespect to the +z axis.
(a) Describe the trajectory of the proton in qualitative terms.Justify your answer in terms of the force on the proton.
(b) Calculate the radius of the trajectory projected onto a planeperpendicular
to the ?eld (i.e., in the x-y plane).
(c) Calculate the period, the frequency, and the angular frequencyof the
motion in the x-y plane.
(d) What is the pitch of the motion (the distance traveled alongthe z axis in one
period of the circular motion in the x-y plane)?
