Summary The force between two point charges is… directly proportional to the magnitude of each charge ( q1 , q2) inversely proportional to square of the separation between their centers ( r) directed along the line connecting their centers ( r) This relationship is known as Coulomb's law. 2. To grow masterfulwith video analysis, curve-fitting and uncertainty. 1. In conclusion, Coulomb's findings can be represented as an equation as follows: F =k 1 2 2 Where k, is the constant of proportionality and is 8.987551787 x 109Nm2/C2, which is closely related to the speed of light in a vacuum. According to Electricity, moving electric charges experience force when kept in a magnetic field. Coulomb's law gives the relationship between the force of an electric field and the distance between two charges: The strength of the force will be inversely proportional to the square of the distance between the charges.
