When a charged particle moves through a magnetic field, the effect of the field changes the particle's
Correct answer: C. Direction of motion.
- A. Mass.
- B. Volume.
- C. Direction of motion.
- D. Energy in the system.
Explanation
When a charged particle moves through a magnetic field, it experiences a magnetic force that acts perpendicular to both its velocity and the magnetic field direction. This force alters the direction of the particle's motion but not its speed or kinetic energy, as the magnetic force does no work. The particle's mass and volume remain constant because they are intrinsic properties unaffected by magnetic forces. Therefore, the correct answer is that the magnetic field changes the direction of motion of the charged particle.

About Charged Particle in a Magnetic Field
A charged particle moving through a magnetic field experiences the Lorentz force, which is perpendicular to both its velocity and the field. The motion may be circular or helical, with questions involving radius, angular frequency, time period, and work done. A stationary charge feels no magnetic force.
