An electron moving with a velocity of 10 7 m/s enters a uniform magnetic field of 1 T, along a direction parallel to the field. What would be its trajectory?

since velocity is parallel to the magnetic field, angle (Ф)=0°
we know F=q(v×b)=qvbsinФ
therefore F=0.
therefore trajectory of the particle is a straight line
this is true for if the velocity is antiparallel to magnetic field also (Ф=180°)
