A positron (q = +e) moves at 4.6 107 m/s in a magnetic field of magnitude 0.50 T. The magnetic force on the positron has magnitude 1.5 10-12 N.
(a) What is the component of the positron's velocity perpendicular to the magnetic field?
m/s
(b) What is the component of the positron's velocity parallel to the magnetic field?
m/s
(c) What is the angle between the velocity and the field?
