Moving Charges and Magnetism question

2003 · Q135

NEETPhysicsMoving Charges and MagnetismMCQ+4 / −1
A charged particle moves through a magnetic field in a firection perpendicular to it. Then the
  1. A
    speed of the particle remains unchanged
  2. B
    direction of the particle remains unchanged
  3. C
    acceleration remains unchanged
  4. D
    velocity remains unchanged
View written solutionFree

Correct answer: A

If a moving charged particle is subjected to a perpendicular uniform magnetic field, then according to F = qvB sin θ\theta θ, it will experience a maximum force which will provide the centripetal force to particle and it will describe a circular path with uniform speed.
