## Charge Formula

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

F = Ke * q₁ * q₂ /r²

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

## Electrical Charge Definition

**What is an electric charge? **An electric charge is a fundamental property of matter that causes a particle to experience a force when subjected to a magnetic field.

## Example Problem

How to calculate charge between points?

**First, determine the magnitude of the charge on the first particle.**For this example, the charge is found to be 10 coulombs on the first particle.

**Next, determine the magnitude of the charge on the second particle.**The second particle is found to have a charge of 20 coulombs.

**Next, determine the distance between the two particles.**The distance between the particles is found to be 5 meters.

**Finally, calculate the electrostatic force.**Using the formula, the electric static force between the charged particles is found to be: 8.98755*10^9 * 10 * 20 / 5^2 = 71900400000 N.
