- The force between two point charges is…
- directly proportional to the magnitude of each charge (q1, q2),
- inversely proportional to square of the separation between their centers (r),
- directed along the line connecting their centers (r).
- This relationship is known as Coulomb's Law.
- As an equation it is usually written in one of two forms…
|F =||k||q1q2||or||F =||1||q1q2|
|ke =||electrostatic constant||ε0 =||vacuum permittivity|
|8.99 × 109 Nm2/C2||8.85 × 10−12 C2/Nm2|
