The ratio of gravitational to kinetic mass for the constituents of matter
Abstract
An analysis of the experiments of Eötvös about the ratio of gravitational to kinetic mass of a few substances yields the result that this ratio for the hydrogen atom, and for the binding energies are equal to that for the neutron with a precision of one part in at least 5.105, and 104 respectively. No conclusion can be drawn about these ratios for the proton and the electron separately.
