* Like charges repel: Particles with the same charge (both positive or both negative) experience a force pushing them apart.
This force is described by Coulomb's Law:
* F = k * q1 * q2 / r²
Where:
* F is the force between the charges.
* k is Coulomb's constant (a proportionality constant).
* q1 and q2 are the magnitudes of the charges.
* r is the distance between the charges.
Key Points:
* The force is proportional to the product of the charges. Larger charges mean a stronger force.
* The force is inversely proportional to the square of the distance between the charges. As the charges get further apart, the force weakens rapidly.
Examples:
* Two protons (both positively charged) will repel each other.
* Two electrons (both negatively charged) will repel each other.
Important Note: The force between charged particles is not limited to the same type of charge. Opposite charges (positive and negative) attract each other.
