Research ArticleOpen accessAll words, across the recordElectron DimensionsRelly Victoria Virgil Petrescu, Raffaella Aversa, Shuhui Li et al.In this study, the theoretical principles necessary to determine the exact magnitude of a moving electron, depending on the speed of movement, will be exposed. The equations are specifically discussed to determine the radius R of the moving electron, which refers to the electron movement velocity v and the resting mass m0. The mechanical moment of inertia of a sphere … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 5 Jun 2017 · 7,582 accessesView PDFCite
