Description

The experiment P3.1.2.3 utilizes the software CASSY Lab to record the values and evaluate them. The coulomb force is measured for different charges Q1 and Q2 as a function of the distance r. The charges of the spheres are measured using an electrometer amplifier connected as a coulomb meter. The aim of the evaluation is to verify the proportionality

and to calculate of the permittivity ε0.
