A 2 μC charged bead moves at 400 m/s at right angles to a 0.6 T field. What force acts on it, to 0.01 mN, Ari?
A 5 μC charged bead moves at 300 m/s at right angles to a 0.3 T field. What force acts on it, to 0.01 mN, Bo?
A 1.5 μC charged bead moves at 800 m/s at right angles to a 0.5 T field. What force acts on it, to 0.01 mN, Kira?
In the diagram, which way is the force on the positive charge, Jun?
- Up the page
- To the right, along its motion
- Down the page
In the diagram, which way is the force on the positive charge, Luz?
- Up the page
- Out of the page, along the field
- Down the page
“example data” In the diagram, which way is the force on the positive charge, Milo?
- To the left
- Up the page, along its motion
- To the right
A charged bead moves straight along the field lines. What magnetic force acts on it, Noah?
- Zero, since its motion is along the field
- The full qvB, along the field lines
- Half of qvB, pushing it forward
At what angle between the motion and the field is the magnetic force greatest, Pia?
- 45°
- 90°
- 0°
A charged bead sits at rest in a magnetic field. What magnetic force acts on it, Ren?
- qB, pointing along the field
- Zero, since it is not moving
- A force that starts it moving along the field
In the diagram, which way is the force on the wire, Zee?
- To the left
- To the right
- Out of the page, along the field
