A charged particle moves through a magnetic field B with a velocity v. Which one of the following statements is true for the force (F) experienced by the particle?
General KnowledgePhysics
- AF is maximum when v and B are parallel to each other.
- BF is maximum when v and B are anti-parallel to each other.
- CF is maximum when v and Bare perpendicular to each other.
- DThe force F is independent of the angle between v and B.
Explanation
The magnetic force on a moving charge is F = qvB sin(theta). It is zero when v is parallel or anti-parallel to B (theta = 0 or 180 degrees) and maximum when v and B are perpendicular (theta = 90 degrees).
