Coulomb's Law Calculator

Formula

The formula to calculate the Electrostatic Force (F) is:

\[ F = K_e \cdot \frac{q₁ \cdot q₂}{r^2} \]

Where:

\( F \) is the electrostatic force between the two objects (N)
\( q₁ \) is the magnitude of the first charge (C)
\( q₂ \) is the magnitude of the second charge (C)
\( r \) is the distance between the charges (m)
\( K_e \) is Coulomb's constant, \( 8.98755 \times 10^9 \, \text{N} \, \text{m}^2 / \text{C}^2 \)

What is Coulomb's Law?

Coulomb's law, also known as the inverse-square law, describes the force between two stationary charged particles. This force, known as the electrostatic effect, is fundamental to the theory of electromagnetism.
