Question

In electrostatics, all electric field lines can only be in three possible forms. Draw the three forms.

Answer 1

Answer :

The electric field is represented by the imaginary lines of force. For the positive charge, the line of force come out of the charge and for negative charge the line of force will move towards the charge.

• 

When the electric field is constant at every point, then the field is called the uniform electric field. The constant field is obtained by placing the two conductor parallel to each other, and the potential difference between them remains same at every point.

• 

The field which is irregular at every point is called the non-uniform electric field. The non-uniform field has a different magnitude and directions.

• 

The following are the properties of an electric field :

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.
