A decelerating electron, e crosses a perpendicular magnetic filed, B that is going into the page. What would be the path of the electron if the deceleration process still undergoes after entering into the magnetic filed? You can neglect the effect of gravity here.

1. Clockwise circular path in the original plane of entry

2. Clockwise spiral in the original plane of entry

3. Anti-clockwise spiral in the original plane of entry

4. Clockwise spiral about a perpendicular axis to both B and to the original path of ee

5. Anti-clockwise spiral about a perpendicular axis to both B and to the original path of e
