Q.
A magnetic field $\overrightarrow{B} = B_{0}\widehat{j}$ exists in the region $a < x < 2a$ and $\overrightarrow{B} = - B_{0}\widehat{j}$, in the region $2a < x < 3a$, where $B_{0}$ is a positive constant. A positive point charge moving with a velocity $\overrightarrow{V} = V_{0}\widehat{i}$, where $V_{0}$ is a positive constant, enters the magnetic field at $x = a$. The trajectory of the charge in this region can be like
A) [image:4_image60.emf]
B) [image:4_image61.emf]
C) [image:4_image62.emf]
D) [image:4_image63.emf]
