If the net external forces acting on the system oif particles is zero, then which of the following may vary?

A neutral particle at rest in a magnetic field decays into two charged particles of different mass. The energy released goes into their kinetic energy. Then what can be the path of the particles. Neglect any interaction between the two charges.
