Xavier College Lorentz Force the Particle Experience Physics Questions I’ve given these problems a try, but I’m not quite sure if I did them correctly. The magnetic force on an alpha particle traveling at constant speed causes it to
move in a circle. Find the time it takes the particle to travel halfway through a
complete circle. Mass of alpha particle = 6.64 x 10-27 kg; B = 0.155 T; q = 1.6 x 10-19
