Question

What is the electric line of force? Mention its properties

Answer 1

here is an electric field around  a charge in which another charge experience a force of attraction or repulsion but the question arise how you represent or visualise this field, the answer is electric field lines. The electric field lines ( electric line of force ) were invented by Faraday 

Answer 2

Answer:

The electric lines of force never cross each other or intersect at a common point because if they did, it would mean two different directions of the electric field at the point of intersection, which is impossible.

Its properties are:

• The relative closeness of the electric lines of force in different regions of space indicates the relative strength of the electric field in different regions.
• The lines of force have a tendency to contract in length like a stretched elastic string. This explains attraction between opposite charges.
• The lines of force has a tendency to separate from each other in the direction perpendicular to their lengths.
• The lines of force are continuous, having no breaks in between. They are imaginary but the electric field they represent is real.
