Description

The experiment P3.1.4.3 consists of a practical investigation of the principle of the image charge. Here, the attractive force acting on a charged sphere in front of a metal plate is measured. This force is equivalent to the force of an equal, opposite charge at twice the distance 2d. Thus, it is described by the formula

First, the force for a given charge Q is measured as a function of the distance d. The measurement is then repeated with half the charge. The aim of the evaluation is to confirm the proportionalities
