According to Coulomb's Law, the force between a pair of charged particles that are brought closer together increases.

Here's why:

* Coulomb's Law: F = k * (q1 * q2) / r²

* F = Force between the charges

* k = Coulomb's constant (a constant value)

* q1 and q2 = magnitudes of the charges

* r = distance between the charges

* Inverse Square Relationship: The force is inversely proportional to the square of the distance between the charges. This means if you halve the distance, the force becomes four times stronger. If you triple the distance, the force becomes nine times weaker.

In summary: As charged particles are brought closer together (r decreases), the force (F) between them increases significantly due to the inverse square relationship in Coulomb's Law.
