Question

What are electric field lines mention two of its properties

Answer 1

Answer:

The region around the electric charge in which the stress or electric force act is called an electric field or electrostatic field.The electric field is represented by the imaginary lines of force called electric field lines.

The following are the properties of an electric field  lines:

1. Field lines never intersect each other.
2. They are perpendicular to the surface charge.
3. The field is strong when the lines are close together, and it is weak when the field lines move apart from each other.
4. The number of field lines is directly proportional to the magnitude of the charge.
5. The electric field line starts from the positive charge and ends from negative charge.
6. If the charge is single, then they start or end at infinity.
7. The line curves are continuous in a charge-free region.
