Question

What is the properties of electric field lines?

Answer 1

Properties of electric field lines are following—

1. Origination and termination, electric field lines are always originate from the positive charge and always terminate from the negative charge.
2. It form looping , it never form clues low like electric field.
3. No interaction between two lines of electric charges. 
4. Relative spacing between lines. Electric field intensity is inversely proportional to specing between them.
5. Line density if the density is more than the electric field line increase and line density decrease then the exerting force also decrease.
