Understanding Coulomb`s Law

Coulomb`s Law describes the electrostatic force between two charged objects. Force charges is proportional product magnitudes charges proportional square distance between centers. Mathematically, expressed as:

F = k * (|q1 * q2|) / r^2


  • F is magnitude force between charges,
  • k is Coulomb`s constant,
  • q1 and q2 are magnitudes charges, and
  • r is distance between charges.
