What will happen if a collection of positive and negative charges are passed at a high speed through a magnetic field which is perpendicular to the direction of motion of the charges? (Assume that both kind of charges are <strong>NOT</strong> going to recombine)
- A. Both kind of charges will stop moving
- B. Positive charges and negative charges will separate out ✓
- C. Positive charges will stop but negative charges will continue moving uninterrupted
- D. Both kind of charges will keep moving uninterrupted
Correct Answer: B. Positive charges and negative charges will separate out
Explanation
According to the Lorentz force law, F = q(v \times B), opposite charges moving in the same direction through a magnetic field will experience forces in opposite directions, causing them to separate.
