Magnetic Effects of Current and Magnetism Part 3

Uniform magnetic fields of different strengths ( B1 and B2 ), both normal to the plane of the paper exist as shown in the figure. A charged particle of mass m and charge q, at the interface at an instant, moves into the region 2 with velocity v 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?
