Electric field strength is influenced by the quantity of charge, distance from the source, and arrangement of field lines.
Electric field strength depends on the quantity of the charge and the distance from the source. The closer the charged objects are, the stronger the force. More charged objects result in a stronger electrostatic force.
Another factor affecting electric field strength is the number of field lines per unit area perpendicular to the lines. These field lines represent the strength of the field, which is also proportional to the closeness of the field lines.
The direction of the electric field is always tangent to the field line at any point in space.
