An alpha (?) particle is traveling at a speed v = 6.70x105 m/s in a west to east direction. A magnetic field, B = 0.882 T, is pointing vertically upward in the region of the alpha particle's motion. Determine the magnetic force exerted on the alpha particle by the magnetic field. Draw a diagram showing the relative velocity, field, and force directions. What is the radius of curvature for the alpha particle as it continues through the magnetic field.
