Coulomb's law describes the force between two point charges. The force is proportional to the product of the charges and inversely proportional to the square of the distance between them.
The Coulomb's Law Calculator helps you calculate the electrostatic force between two point charges based on the charges and the distance between them. Using Coulomb’s Law formula:
F = kₑ * |q₁ * q₂| / r²
Where:
Coulomb's Law describes the force between two charges. The magnitude of the force depends on the magnitudes of the charges and the distance between them. The force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
The force can either be attractive or repulsive:
Let's consider two positive charges:
Using Coulomb's Law, the force F is:
F = (8.99 × 10⁹) * |(3 × 10⁻⁶) * (5 × 10⁻⁶)| / (2)²
F = 0.0337 N (repulsive force)
Let’s calculate the force between:
Using Coulomb's Law, the force F is:
F = (8.99 × 10⁹) * |(2 × 10⁻⁶) * (-4 × 10⁻⁶)| / (1)²
F = 0.0719 N (attractive force)
Coulomb's Law plays a crucial role in the study of electrostatics and electromagnetism. It is fundamental to understanding how charged particles interact in electric fields and is applied in areas like:
Understanding Coulomb’s Law is essential for applications in electronics, chemistry, and material science.
Coulomb's Law helps us understand the fundamental forces between charged particles, which is crucial for understanding many phenomena in both everyday life and advanced technologies. Using this law, we can calculate the electrostatic force between charges and explore the interactions that shape the behavior of particles and materials in electric fields.
