A magnetic field \(B=B_{0} \hat{j}\)exists in the region a < x < 2a
and \(B=-B_{0} \hat{j}\) in the region
2a < x < 3a, where B0 is a
positive constant. A positive point charge moving with a velocity \(\vec{v}=v_{0} \hat{i}\) where v0 is
a positive constant, enters the magnetic field at x = a. The trajectory of the charge in this region can be like,
