23. An electron moves in the plane of the page through two regions of space along the dotted-line trajectory shown in the figure. There is a uniform electric field in Region I directed into the plane of the page (as shown). There is no electric field in Region II. What is a necessary direction of the magnetic field in regions I and II? Ignore gravitational forces.| Region I | Region II | |
|---|---|---|
| A) | Toward bottom of page | Up on the page |
| B) | Toward top of page | Into the page |
| C) | Toward top of page | Out of the page |
| D) | Toward bottom of page | Out of the page |
