Charge Calculator

Enter the magnitude of the charge of two points and the distance between them into the calculator to determine the charge or force between them.

Charge Formula

The following equation is used to calculate the charge between two points.

F = Ke * q₁ * q₂ /r²

  • F is the electrostatic force between the two objects
  • q1 is the magnitude of the first charge
  • q2 is the magnitude of the second charge
  • r is the distance between them
  • Ke is coulomn’s constant which is equal to 8.98755 * 10⁹ N * m² / C²
