An experimental investigation of the influence of an electrostatic potential on electron mass as predicted by Weber's force law

Assis (J. Phys. Soc. Jpn.} 62, 1418 (1993.) showed that Weber's force law between moving charges leads to the conclusion that the inertial mass of an electron depends on the charges that surround it. The experimental confirmation of this effect was claimed by Mikhailov (Annal. Fond. Louis de Broglie, 24, 161 (1999).) who detected frequency changes of a glow discharge lamp oscillator as a function of the voltage applied to the shield surrounding …
