Question

As you know, the general shape of the trajectory executed by a charged particle in the uniform magnetic field is a helix. A helix is characterized by its radius r in the plane perpendicular to the axis of the helix and by pitch p along the axis.

In this problem, a positively charged particle of mass m=1.17 g and charge q=1.166 mC is injected into the region of the uniform magnetic field

B=B_yj+B_zk

with the initial velocity

v=v_xi+v_yj.

Find parameters r and p of its resulting helical trajectory if B_y=0.356 T, B_z=0.626 T, v_x=10.2 cm/s, v_y=5.28 cm/s:
r = ___ cm,

p = ___ cm.
