It was shown (J. Phys. Soc. Jpn. 62, 1418 (1993).) that Weber’s force law predicts an influence upon the apparent inertial mass of electrically charged particles in relative motion. The magnitude of this change in inertial mass, called Weber’s mass, depends on the relative motion (both speed and acceleration) and the relative spatial distribution of the particles. A special case was analytically solved, in which the motion of a single point charge was considered that is surrounded by a static and fixed spherical surface with a homogeneous charge distribution. The first experimental test of the prediction showed positive results (Annal. Fond. Louis de Broglie, 24, 161 (1999).). Two reproductions were carried out, in which null results were reported together with an explanation for the previous positive result. It was suggested that a possible reason for the null result in the experimental setup could be that the charges could freely move on the surface. We set out to reproduce all previous experiments in o...
