when charged particle enters the magnetic field parallel, it will:
Correct answer: C. Move straight
- A. Deflect toward north
- B. Deflect toward south
- C. Move straight
- D. Move in circular path
Explanation
In this orientation, the magnetic force on the particle is perpendicular to its velocity, causing it to move in a straight line without any deflection.

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.
