F = k * (q1 * q2) / r²
Where:
* F is the force between the charges
* k is Coulomb's constant (approximately 8.98755 × 10⁹ N⋅m²/C²)
* q1 and q2 are the magnitudes of the charges
* r is the distance between the charges
Key Points:
* The force is inversely proportional to the square of the distance. This means that if you double the distance, the force becomes four times weaker.
* If the charges are of opposite signs, the force is attractive.
* If the charges are of the same sign, the force is repulsive.
In summary: As the distance between charges increases, the electrostatic force between them weakens significantly, following an inverse square relationship.
