009 (part 1 of 3) 10.0 points A proton travels with a speed of 4.8×106 m/s at an angle of 96◦ west of north. A magnetic field of 4.6 T points to the north. Find the magnitude of the magnetic force on the proton. (The magnetic force experienced by the proton in the magnetic field is proportional to the component of the proton’s velocity that is perpendicular to the magnetic field.)
