The strength of the electric field each particle exerts on the other decreases with the square of the distance between them. This is known as Coulomb's Law.

Here's a breakdown:

* Coulomb's Law: This fundamental law of electrostatics describes the force between two charged particles. It states that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

* Electric Field: An electric field is a region around a charged particle where another charged particle would experience a force. The strength of the electric field is determined by the charge of the source particle and the distance from it.

* Inverse Square Law: The "inverse square" part of Coulomb's Law means that if you double the distance between two charged particles, the electric field strength decreases to one-fourth of its original value. If you triple the distance, the field strength decreases to one-ninth.

In summary:

* Closer particles: Experience stronger electric fields.

* Further particles: Experience weaker electric fields.

Important Note: The electric field strength also depends on the magnitude of the charges. Larger charges produce stronger electric fields.
