In the figure shown,a charge $q$ of mass $m$ moving with a velocity $v$ along the $x$-axis enters a region of uniform magnetic field $B$ directed into the page. If the particle is able to enter the region $x > b$,then the velocity $v$ must be greater than:
- A$\frac{qBb}{m}$
- B$\frac{qBa}{m}$
- C$\frac{qB(b-a)}{m}$
- D$\frac{qB(b+a)}{2m}$
