CAPILLARY METHOD OF MEASUREMENT free fall acceleration BODIES AND DEVICE FOR ITS IMPLEMENTATION

摘要

1. A method for measuring the gravitational acceleration of bodies, characterized in that the capillary inner radius r is placed in the wetting liquid, the level of which under the action of Laplace pressure equal to the hydrostatic pressure of the liquid rises to a height h, which is related to the magnitude of the gravitational acceleration g addiction, where p - liquid density, and σ - surface tension coefficient zhidkosti.2. The method for measuring gravitational acceleration body according to claim 1, characterized in that the plate capacitor is placed in the wetting fluid container C which is related to the magnitude of the gravitational acceleration g dependency where σ - coefficient of surface tension of the liquid, ρ - density of the fluid, ε- dielectric body with capillary permeability, ε- permittivity of the fluid used, and - the width of the capacitor plate, b - length of the capacitor plates, d - the distance between the electrodes kondensatora.3. The method for measuring gravitational acceleration body according to claim 2, characterized in that the oscillation capacitance can be converted into an electrical signal that can detect, transform and process the electronic computing blok.4. An apparatus for measuring the gravitational acceleration of bodies, characterized in that it comprises a flat capacitor between the plates of which the working fluid is formed of a set of thin capillaries, the working electrode and the body placed in a container with a wetting zhidkostyu.5. An apparatus for measuring gravitational acceleration body according to claim 4, characterized in that the working body is a flat capacitor between the plates, MY
