9.2 Coulomb's law (ESBPJ)

Like charges repel each other while unlike charges attract each other. If the charges are at rest then the force between them is known as the electrostatic force. The electrostatic force between charges increases when the magnitude of the charges increases or the distance between the charges decreases.

The electrostatic force was first studied in detail by Charles-Augustin de Coulomb around 1784. Through his observations he was able to show that the magnitude of the electrostatic force between two point-like charges is inversely proportional to the square of the distance between the charges. He also discovered that the magnitude of the force is proportional to the product of the charges. That is: \[F \propto \frac{Q_1 Q_2}{r^2},\] where \(Q_1\) and \(Q_2\) are the magnitudes of the two charges respectively and r is the distance between them. The magnitude of the electrostatic force between two point-like charges is given by Coulomb's law.

Coulomb's law

Coulomb's law states that the magnitude of the electrostatic force between two point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them. \[F = \frac{k Q_1 Q_2}{r^2}\]

The proportionality co

August 23 marks the passing of Charles-Augustin de Coulomb. Coulomb was a French military engineer known for his work with static electricity.

Coulomb is best known for Coulomb’s law. This law is a statement of the force between two electric charges being inversely proportional to the square of the distance between them. and directly proportional to the amount of charge.

where Q₁ and Q₂ are the charges and r is the distance between them. If the two charges have the same sign (both positive or negative charge), the force is a repulsive force. If they have different signs (one positive and the other negative) the force is attractive.

Coulomb designed a device called a torsion balance to measure very small forces. The torsion balance consists of a bar suspended by a thin wire ribbon. The ribbon acts as a very weak spring that will twist when forces act on the ends of the bar. The greater the twist, the greater the force. Typically, this device is enclosed in an air tight container so air currents won’t move the bar.

Coulomb’s balance was an insulating rod with a metal coated ball on one end suspended by a silk ribbon. He charged the ball with a known amount of static electricity and brought another similarly charged ball close. He then measured the
