A magnetic field →B=B0 ^j exists in the region a<x<2a and →B=−B0 ^j in the region 2a<x<3a, where B0 is a positive constant. A positive point charge moving with a velocity →v=v0 ^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, |
