A charged particl

Answer :

As we know the force on a charged particle in a magnetic field is given by

Where q = charge of the particle ,

          v = velocity of particle and B is the magnetic field in that region.

The force exerted on a charged particle in a magnetic field only exist if the velocity of the particle is perpendicular to the direction of the magnetic field as the equation  suggest. 
If velocity has a component along B, this component remains unchanged as the motion along the magnetic field will not be affected by the magnetic field. The motion in a plane perpendicular to B is as before a circular one, thereby producing a helical motion

Thus the described path will be helical as shown in the figure and the velocity's parallel component will make the particle move along the direction of the field.
