Uniform magnetic fields of different strengths ( 
and 
), both normal to the plane of the paper exist as shown in the figure. A charged particle of mass 
and charge 
, at the interface at an instant, moves into the region 2 with velocity 
and returns to the interface. It continues to move into region 1 and finally reaches the interface. What is the displacement of the particle during this movement along the interface?
(Consider the velocity of the particle to be normal to the magnetic field and 
)
