A salt molecule breaks down into a sodium ion $($Na$+)$ and a chlorine ion $($Cl$-).$ Both initially move with the same speed, in the same direction, and at $\backslash (90^\{\backslash$circ$\}\backslash )$ with respect to a uniform magnetic field. Each ion experiences a magnetic force that is:

equal in magnitude but perpendicular to each other in opposite directions and differ by the ratio of their masses. equal in magnitude but opposite in direction in the same direction but the magnitude differ by the ratio of their masses. identical
