(A) When a charged particle is released from rest in a region where electric field $\vec{E}$ and magnetic field $\vec{B}$ are parallel to each other,the magnetic force $\vec{F}_m = q(\vec{v} 	imes \vec{B})$ is zero because the initial velocity $\vec{v} = 0$.As the particle starts moving due to the electric force $\vec{F}_e = q\vec{E}$,its velocity $\vec{v}$ becomes parallel to the electric field $\vec{E}$.Since $\vec{E}$ is parallel to $\vec{B}$,the velocity $\vec{v}$ remains parallel to the magnetic field $\vec{B}$ at all times.Because $\vec{v} \parallel \vec{B}$,the magnetic force $\vec{F}_m = q(\vec{v} 	imes \vec{B})$ remains zero throughout the motion.The particle is only acted upon by the electric force,which causes it to accelerate in a straight line along the direction of the electric field.

$A$ charged particle is released from rest in a region of steady and uniform electric and magnetic fields which are parallel to each other. The particle will move in a
