In a region, steady and uniform electric and magnetic fields are present. These two fields are parallel to each other. A charged particle is released from rest in this region. The path of the particle wiII be
Let E and B be the electric and magnetic fields respectively applied along X-axis as shown in fig
When a charged particle is released from rest, it will experience an electric force in the direction of electric field or opposite to the direction of electric field depending upon the nature of the charge. Due to this force, the charged particle acquires some velocity along X-axis. Due to this motion of charge, the magnetic force cannot have non-zero value because the angle between v and B would be either 0°or 180°. Therefore, only electric force is acting on the particle. At a result, the path will be along a straight line
