Three positively charged particles, labeled \(X\), \(Y\), and \(Z\), are injected into a region containing a uniform magnetic field of magnitude \(B\) directed perpendicular to their velocities. Each particle undergoes uniform circular motion within the field. The graph displays the radius \(r\) of the circular path as a function of speed \(v\) for each particle.

Which of the following statements is correct regarding the particles based on the graph?
