Question

Question 5 5 pts A charged particle traveling at a given speed enters a uniform magnetic field. The velocity vector of the particle is perpendicular to the magnetic field. Which of the following particle properties will change while in the magnetic field? Its speed. Its velocity Its kinetic energy. O All of the above (A, B, and C). None of the above (not A. B, or C).

Answer 1

When a charged particle travelling at a given speed enters perpendicular to a magnetic field, the magnitude of speed remains constant. But, the direction of speed or motion constantly changes as the particle will move in a circular path in a magnetic field. Therefore, the velocity of particle changes due to the continuous change in direction, eventhough its magnitude does not change.

So, the property of particle which changes while in magnetic field is its velocity.
