A charged particle moves through a magnetic field B with a velocity v. Which one of the following statements is <strong>true</strong> for the force (F) experienced by the particle?
- A. F is maximum when v and B are parallel to each other.
- B. F is maximum when v and B are anti-parallel to each other.
- C. F is maximum when v and B are perpendicular to each other. ✓
- D. The force F is independent of the angle between v and B.
Correct Answer: C. F is maximum when v and B are perpendicular to each other.
Explanation
The magnetic force on a moving charge is F = qvB \sin(\theta). It is maximum when the angle \theta between velocity v and magnetic field B is 90^\circ (perpendicular).
