Sample Questions in this Chapter

QUESTION #0 Motion of Charged Particle in Magnetic Field
Uniform magnetic fields of different strengths (mathrmB_1 and mathrmB_2) , 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? {{IMG1}} (Consider the velocity of the particle to be normal to the magnetic field and mathrmB_2 > mathrmB_1 )
