Question
A particle of mass m and charge q, moving with velocity V enters Region II normal to the boudary as shown in fig. Region II has a uniform magnetic field B perpendicular to the plane of the paper. The length of the Region II is l . Then :

- The particle enters Region III only if its velocity
- Path length of the particle in region II is maximum when velocity
- Time spent in Region II is same for any velocity V as long as the particle returns to Region I.
- All the above are correct
The correct answer is: All the above are correct
