Problem 2 - Olympiad

A charged particle enters a uniform magnetic field at an angle θ with its initial velocity. If the magnetic field is in the +x direction and the initial velocity has components in both +y and +z directions, what is the shape of its trajectory?

Correct: B

The particle's motion has two components: perpendicular and parallel to the magnetic field. The perpendicular component causes circular motion, while the parallel component remains unaffected. The combination of these motions results in a helical path.
