  1. Coulomb’s law law of physics describing the electrostatic interaction between electrically charged particles.

  2. Coulomb’s law The magnitude of the electrostatic force of interaction between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them.

  3. Coulomb’s law equation F = force in Newtons (N) q1 and q2 = charges in Coulomb (C) r = distance between q1 and q2 in meters (m) k = Coulomb constant = 9.0 x 109 Note: Do not include the signs of the charges when using this equation. Remember: If the signs of the charges are the same, the force is repulsive. If the signs are different (i.e., one positive and one negative), the force is attractive.
