A magnitude field $B=B_{0}j^ $ exists in the region $a<x<2aandB=−B_{0}j^ $, in the region $2a<x<3a$, where $B_{0}$ is a positive constant. A positive point charge moving with a velocity $v=v_{0}i^$, where $v_{0}$ is a positive constant, enters the magnetic field at $x=a$ . The trajectory of the charge in this region can be like,
