Experimento de charles coulomb family

Charles-Augustin de Coulomb (June 14, 1736 – August 23, 1806), a French engineer and physicist, discovered the relationship between the force that exists between two electrically charged bodies and the distance that separates them, known as Coulomb's Law.

World Book's Biographical Encyclopedia of Scientists. In the midst of the French revolution, he retired from the Corps du Genie, and continued his research from a home in Blois. He also played a role in ensuring Paris's water suppply. This was lucky for Coulomb, since he received the credit and fame for this spectacular discovery.

He developed his theories while attempting to investigate the law of electrical repulsions. In this way Coulomb showed that the force depended inversely on the square of the distance between the spheres, like Newton's gravitational force.

If the charges have the opposite sign, the forces are antiparallel to the interparticle vectors, i.e. This article abides by terms of the Creative Commons CC-by-sa 3.0 License (CC-by-sa), which may be used and disseminated with proper attribution.

From the early 1780s to the first decade of the 1800s, Coulomb continued to be involved with public life as the turbulent politics of those times permitted.

Dictionary of Scientific Biography. It was during this time that he showed, using his previously perfected tortion balance, that the electrical force between charged bodies varies inversely as the square of the distance between them, and is porportional to the charge of each, being an attractive force for opposite charges, and a repelling force for charges of the same kind.

1982. 8th ed. The formula to Coulomb's Law is of the same form as Newton's Gravitational Law: The electrical force of one body exerted on the second body is equal to the force exerted by the second body on the first.

Biography

Coulomb was born in Angoulême, France.

In the figure above, F21 means “the force of charge q2 on charge q1” or more simply “the force of 2 on 1”.

Torsion Balance

Charles Augustin de Coulomb invented the torsion balance which could measure electrostatic force. Chicago: World Book. Inside the balance are two pith balls.
