$A$ particle of mass $M$ and charge $q$ moves with a constant velocity $V$ in the positive $x$-direction. $A$ constant magnetic field $B$ exists in the negative $z$-direction between $x = a$ and $x = b$. Find the minimum value of $V$ such that the particle enters the region $x > b$.
- A$qbB/M$
- B$q(b - a)B/M$
- C$qaB/M$
- D$q(b + a)B/2M$
