Frequently asked questions
- What is Coulomb's constant k?
- k = 1/(4πε₀) ≈ 8.9875×10⁹ N·m²/C², where ε₀ is the permittivity of free space. It appears in all electrostatic force calculations.
- What is a typical charge magnitude?
- 1 μC (1×10⁻⁶ C) is typical in electrostatics experiments. An electron carries 1.602×10⁻¹⁹ C.
