    Ans=(3)...explain

    the velcotity in direction of electirc field will get changed due to work done by electirc field on it .
    but the other component of velocity perpedicualar to field wont get effected. hence a parabolic path



  • @sri
    Let electric field be in the upward Y direction and charge be a positive point charge.

    X direction is perpendicular to Y direction. In short X is horizontal .

    This is exactly similar to the situation of projectile motion in which gravitational acceleration is in negative Y direction.

    No need to say that trajectory is parabola.
