Magnetic field due to currentHard
Question
A magnetic field 
exists in the region a < x < 2a and 
, in the region 2a < x < 3a, where B0 is a positive constant. A positive point charge moving with a velocity 
, where v0 is a positive constant, enters the magnetic field at x = a. The trajectory of the charge in this region can be like
exists in the region a < x < 2a and , in the region 2a < x < 3a, where B0 is a positive constant. A positive point charge moving with a velocity , where v0 is a positive constant, enters the magnetic field at x = a. The trajectory of the charge in this region can be like Options
A.
B.
