WebInstitute of Physics WebIn this experiment, you will verify the validity of Coulomb’s law by measuring the force acting between two charged spheres. The force will be measured by means of a torsion balance: in your setup you will produce a repulsion between a fixed sphere and another one mounted on a rod, counter-balanced and suspended from a thin torsion wire.
