✓✓In a region steady and uniform electric current and magnetic field are present these two fields are parallel to each other. A charged particle is released from rest in this region .the path of particle will be___________

$\sf\star{\underline{ANSWER:-}}$

$\sf\implies\pink{{Straight\:line}}$

$\sf\star{\underline{EXPLANATION:-}}$

❍ Let E and B be along x-axis. When a charged particle is released from rest, it will experience an electric force along the direction of an electric field or opposite to the direction of electric field depending on the nature of the charge.

❍ Due to this force, it acquires some velocity along the x-axis. Due to this motion of charge, magnetic force cannot have non-zero value because of angle between v and B would be either 0° or 180°.

❍ So, only electric force is acting on the particle and hence it will move along a straight line.
