An alpha particle (2 protons and 2 neutrons) is traveling with a velocity of = (0.500 + 1.00 + 1.00k) x 1062 in a magnetic field B = (-0.500f + 0.300 + 0.800k) 10-T. a) What is the force on the alpha particle? b) What is the angle between the velocity and the magnetic field? c) Briefly describe the trajectory of the alpha particle in the magnetic field.
