A charged particle is injected into a uniform magnetic field such that its velocity vector is perpendicular to the magnetic field lines. Ignoring the particle's weight, the particle will
A) follow a circular path.
B) follow a spiral path.
C) move along a parabolic path.
D) move in a straight line.

Question

Quizplus · Accepted Answer

When a charged particle moves perpendicular to a uniform magnetic field, it experiences a magnetic force perpendicular to its velocity, causing it to move in a circular path. This is due to the Lorentz force acting on the particle.
