Question

A charge particle moving in magnetic field \( B \), has components of velocity along \( B \) as well as perpendicular to \( B \). The path of the charge particle will be:

• A. Helical path with the axis perpendicular to the direction of magnetic field \( B \)
• B. Straight along the direction of magnetic field \( B \)
• C. Helical path with the axis along magnetic field \( B \)
• D. Circular path

Hint:

In the presence of a magnetic field, the motion of a charged particle can be analyzed in terms of components:
Parallel component: causes linear motion along the field.
Perpendicular component: causes circular motion, resulting in helical motion when combined with the parallel component.
