Understanding Coulomb’s Law: The Fundamentals of Electrostatic Interaction
Coulomb’s law, named after physicist Charles-Augustin de Coulomb, is the cornerstone of electrostatics. It describes the force of attraction or repulsion between two charged objects. This force, known as the electrostatic force, is directly proportional to the product of the charges and inversely proportional to the square of the distance between their centers. Think of it this way: stronger charges attract or repel each other more powerfully, and as the objects move further apart, the force weakens.
The law can be mathematically expressed as:
Where:
- F is the electrostatic force
- k is Coulomb’s constant (approximately 8.98755 × 10^9 N⋅m^2/C^2)
- q1 and q2 are the magnitudes of the two charges
- r is the distance between the centers of the charges
