What is Coulomb's torsion balance?
Figure 1: (a) Coulomb's torsion balance: A pith ball (lower right corner) is attached on a rotating beam with a counterweight on the opposite end. When a second pith ball (upper left corner) of equal charge is brought near the rst ball, they will repel, and the beam starts to rotate (Source: Coulomb, 1785). (b) A pith ball electroscope.
Why did Charles Augustin de Coulomb use a torsion balance?
In 1786, French scientist, Charles Augustin de Coulomb utilized a torsion balance of his design to observe the effects of charges interacting with one another, which lead to the development of his law known as Coulomb’s Law.
Is a torsion balance experiment possible?
17 Martinez, “Coulomb’s Torsion Balance Experiment” (ref. 9), 547. possible due to a source of error that is most likely unavoidable. This source of error has
What equipment was used in Coulomb's torsion balance experiment?
