The particle enters Region III only if its velocity $$v > {{qlB} \over m}$$

The particle enters Region III only if its velocity $$v < {{qlB} \over m}$$

Path length of the particle in Region II is maximum when velocity $$v = {{qlB} \over m}$$

Time spent in Region II is same for any velocity v as long as the particle returns to Region I
