For c=2a if, the magnetic field at point P will be zero when

A magnetic field B=B_(0)hatj exists in the region a lt x lt 2a and B=-B_(0)hatj , in the region 2a lt x lt 3a , where B_(0) is a positive constant. A positive point charge moving with as velocity v=v_(0)hati , 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:
