Three charged objects with the same mass and the same magnitude charge have initial velocities directed right. They enter a region of uniform magnetic field from the left. You can see the trails they follow as the move through the field. Rank the objects based on their speeds.

1. 1 > 2 > 3
2. 2 > 1 > 3
3. 3 > 2 > 1
4. 3 > 1 > 2
5. None of the above

The radius of the path is proportional to the speed, so 2 > 1 > 3.

Rank the objects based on the magnitude of the force they experience as they travel through the magnetic field.

1. 1 > 2 > 3
2. 2 > 1 > 3
3. 3 > 2 > 1
4. 3 > 1 > 2
5. None of the above

The force is also proportional to the speed, so 2 > 1 > 3.
