A proton moving at speed v = 1.00 x 106m/s enters a region in space where a magnetic fi eld given by B= (–0.500 T) z exists. The velocity vector of the proton is at an angle θ= 60.0° with respect to the positive z-axis.
a) Analyze the motion of the proton and describe its trajectory (in qualitative terms only).
b) Calculate the pitch of the motion (the distance traveled by the proton in the direction of the magnetic field in 1 period).
73. A uniform magnetic field of magnitude 0.150 T is
directed along the positive x axis. A positron moving at
a speed of 5.00 × 10º m/s enters the field along a direc-
tion that makes an angle of 0 = 85.0° with the x axis
(Fig. P29.73). The motion of the particle is expected
to be a helix as described in Section 29.2. Calculate
