QUESTION 10 A negatively-charged particle is slowly moving as it enters a region that has a constant magnetic field. If the velocity of the particle is initially parallel to the magnetic field, what will be the subsequent motion of the particle? It will follow a circular path in a plane parallel to the magnetic field lines. It will follow a circular path in the plane perpendicular to the magnetic field lines. It will follow a straight line path in the same direction as it was initially traveling. It will follow a helical path around the magnetic field lines.
