Step-by-step explanation:
The expression from electric field is as follows;

Here, E is the electric field, k is constant, r is the distance and [tex]q is the charges.
The electric field is inversely proportional to the distance. It is directly proportional to the charge.
As the distance from the source charge increases the electric field also gets decreased. The electric field gets increased if the distance from the source decreases.
The electric field lines are the surrounding around the charges in which the force due to the electric field can be experienced.
The electric field is strongest near the charged object.
