Hello Ekta, No problem I hope the following explanation will clear your understanding about elctric field lines.

Electric field lines are a visual representation used to depict the direction and strength of the electric field around electric charges or distributions of charges. They provide a way to visualize the behavior and influence of electric fields in a given region.

Electric field lines have the following properties:

1. Direction: Electric field lines point in the direction of the electric field at any given point. The direction is from positive charges towards negative charges. Therefore, field lines emanate from positive charges and terminate on negative charges.

2. Density: The density of electric field lines represents the strength of the electric field. The closer the lines are to each other, the stronger the field in that region. Conversely, when the lines are farther apart, the field is weaker.

3. Perpendicularity: Electric field lines are always perpendicular to the surface of a conductor at equilibrium. This property indicates that the electric field inside a conductor is zero.

4. Continuity: Electric field lines are continuous curves or lines. They cannot start or end abruptly in space, nor can they intersect each other. This property ensures that each field line represents a unique path for a hypothetical positive test charge.
