A particle of mass m and charge q, moving with velocity V enters Region II normal to the boundary as shown in the
figure. Region II has a uniform magnetic field B perpendicular to the plane of the paper. The length of the Region II is
A. Choose the correct choice(s).
Select ALL correct options:
A
The particle enters Region III only if its velocity $\mathrm{V}>\frac{\mathrm{q} \ell \mathrm{B}}{\mathrm{m}}$
B
The particle enters Region III only if its velocity $\mathrm{V}<\frac{\mathrm{q} \ell \mathrm{B}}{\mathrm{m}}$
C
Path length of the particle in Region II is maximum when velocity $V=\frac{q \ell B}{m}$
D
Time spent in Region II is same for any velocity V as long as the particle returns to Region I
