Question

What is an electric line of force and give the properties of electric lien of force.​

Answer 1

$\huge\bold\red{꧁Hello\:Mate꧂ }$

An electric line of force is a smooth curve drawn in the electric field so that the tangent at any point on the curve gives the direction of electric field at that point. Properties: Lines of force are continuous curves, which start from a positive charge and end on a negative charge.

Answer 2

Answer

Electric line of force is the path along which a test charge moves.

Characteristics of lines of force :

$\bigstar$ They start from a positive charge and end to a negative charge.

$\bigstar$ They are parallel and equally spaced in uniform field.

$\bigstar$ Tangent drawn to a line of force at any point gives the direction of the resultant electric field at that point.

$\bigstar$ They never intersect each other.

$\bigstar$ They are dense where the field is strong and they are less dense where the field is weak.

$\bigstar$ They do not pàss through the conductor.

$\bigstar$ They exert lateral stress on one another.

$\bigstar$ They are always perpendicular to the surface of a charged conductor.
