What will be the path of a charged particle moving along the direction of a uniform magnetic field?

What will be the path of a charged particle moving perpendicular to a uniform magnetic field ?

Describe qualitatively the path of a charged particle moving in a region with uniform electrosatic and magnetic fields parallel to each other, with initial velocity at an arbitrary angle with common direction of the fields.

What is the direction of force acting on a charged particle q, moving with a velocity in a uniform magnetic field?

Fill ups ……………acts on the charge moving along the direction of magnetic field.

Why does not a charged particle moving at right angle to the direction of a magnetic field undergo any change in kinetic energy?
