$A$ charged particle of mass $m$ and charge $q$ is projected with velocity $v$ into a region of uniform magnetic field $B$ confined between two parallel plates separated by a distance $d$,as shown in the figure. What is the condition for the charged particle not to strike the opposite plate?
- A$B > \frac{qd}{mv}$
- B$B < \frac{mv}{qd}$
- C$B < \frac{qd}{mv}$
- D$B > \frac{mv}{qd}$
