Moving Charges and Magnetism

Question:

A charge particle is moving on a helical path in a uniform magnetic field. The correct statement describing the velocity of this charge particle, is:

Options:

The particle has non-zero components, of velocity along the parallel as well as perpendicular directions of magnetic field

The particle velocity is in a direction parallel to the direction of magnetic field

The particle velocity is in a direction perpendicular to the direction of magnetic field

The particle is initially at rest while switching the magnetic field on

Correct Answer:

The particle has non-zero components, of velocity along the parallel as well as perpendicular directions of magnetic field

Explanation:

The correct answer is Option (1) → The particle has non-zero components, of velocity along the parallel as well as perpendicular directions of magnetic field

As charge particle is moving in helical path therefore it have non-zero components of velocity, along parallel as well as normal to magnetic field.
