摘要: A free-fall technique has been used to measure the net vertical component of force on electrons in a vacuum enclosed by copper tube. This was shown be less than $0.09mg$, where $m$ is inertial mass electron and $g$ 980 cm/${\mathrm{sec}}^{2}$. supports contention that gravity induces an electric field outside metal surface, magnitude direction such gravitational cancelled.
