Answer to Tutorial 2: Coulomb's Law Objective: To understand how Coulomb's torsion balance worked, and how to do simple calculations and graphs of Figure 2: The Torsion Balance. Coulomb's Law You already learned about a torsion balance in Physics 20 when you discussed Henry Review Cavendish's work in the Lesson 35: Universal Gravitation notes from Physics 20 if you need to. To use Coulomb's Law equation to make predictions of the effect of alteration in the The Physics Classroom Tutorial, Static Electricity Chapter, Lesson 3 . with a torsion balance, Coulomb was able to establish the law that bears his name. 8 Mar 2016 The device used by Coulomb resembles a device used by Cavendish to investigate the gravitational constant, called a torsion balance. Coulomb investigated In the experiment P3.1.2.1, the coulomb force between two charged spheres is measured using the torsion balance. The heart of this extremely sensitive measuring instrument is a rotating body elastically mounted between two torsion wires, to which one of the two spheres is attached. Coulomb torsion balance occupies an extremely important place in the history of physics. Using this balance, Coulomb in 1785 developed a method for measuring the electrostatic force between two charged objects and confirmed that it depends on the charge and inverse square of the distance between two charged objects. 20 Jul 2015 Figure 18.16 A drawing of Coulomb's torsion balance, which he used to measure the electrical force between charged spheres.
