Torsion Balance-Coulombo's Law

U diplomskom radu predstavljen je Coulombov zakon te eksperiment za potvrdu tog zakona pomoću torzijske vage. Cilj rada bio je prikazati povijesni prikaz otkrića Coulombova zakona, definirati i matematički zapisati taj zakon te ga eksperimentalno potvrditi izvedbom pokusa pomoću torzijske vage. Kao uvod u problematiku rada opisana je Coulombova metoda potvrde zakona, a ujedno je prikazana i matematička teorijska podloga. Glavni dio rada isključivo je eksperimentalne prirode i temelji se na pripremi postava torzijske vage u laboratoriju Odjela za fiziku te izvedbi eksperimenta u svrhu dokazivanja Coulombova zakona. Eksperiment je podijeljen na dva dijela kako bi ispitali različite ovisnosti kuta otklona (sile). U posljednjem dijelu rada, podaci dobiveni iz oba dijela eksperimenta, se tablično i grafički analiziraju te se provjerava potvrda Coulombova zakona elektrostatike.This master thesis presents Coulomb's law and experiment with torsion balance as confirmation of this law. The purpose of this paper is to present historic discovery of Coulomb's law, to determine mathematically this law and to experimentally analyze and confirm this law with torsion balance as main device. As an introduction to this paper we gave the explanation of Coulomb's method of finding the law and after that we analyzed in detail theoretical mathematical background of this law. The main part of the paper is of experimental nature and is based on preparation of torsion balance in possession of our Department of Physics and performing the actual experiment for confirming the law. Experiment is divided into two parts with purpose of testing different dependences of torsion displacement angle (force). In the last part, there are shown graphic and tabular analysis of data collected from both parts of experiment with purpose of confirming the Coulomb's law of electrostatics
