1. Identify the direction of the magnetic field (B) and the velocity (v) of the charged particle in each scenario.
2. Use the right-hand rule to determine the direction of the magnetic force (F) on a positive charge.
- Point your fingers in the direction of the velocity (v).
- Curl your fingers in the direction of the magnetic field (B).
- Your thumb points in the direction of the force (F) for a positive charge.
3. For a negative charge, the force direction is opposite to that determined by the right-hand rule.
4. Apply the right-hand rule to each case:
- Case a: B is into the page (×), v is to the right. F is upward.
- Case b: B is out of the page (•), v is to the right. F is downward.
- Case c: B is downward, v is to the right. F is into the page (×).
- Case d: B is out of the page (•), v is to the left. F is downward.
5. Verify the force direction using the cross product formula: F = q(v × B).
6. Confirm the direction of the force in each case matches the right-hand rule and the cross product result.
