Problem

Two identical alpha particles (each carrying a charge of +2e+2e) move through the same uniform magnetic field. Particle 1 travels parallel to the field, while Particle 2 travels antiparallel. Which statement correctly compares the magnitudes of the magnetic forces on the two particles? (a) Particle 2Particle\ 2 experiences a larger magnetic force than Particle 1Particle\ 1. (b) Particle 1Particle\ 1 experiences zero magnetic force, while Particle 2Particle\ 2 experiences a non-zero\text{non-zero} magnetic force. (c) Both particles experience zero magnetic force. (d) Both particles experience the same non-zero\text{non-zero} magnetic force.
