A Subnano-g Electrostatic Force-Rebalanced Flexure Accelerometer for Gravity Gradient Instruments

A subnano-g electrostatic force-rebalanced flexure accelerometer is designed for the rotating accelerometer gravity gradient instrument. This accelerometer has a large proof mass, which is supported inversely by two pairs of parallel leaf springs and is centered between two fixed capacitor plates. This novel design enables the proof mass to move exactly along the sensitive direction and exhibit...

AN ELECTROSTATIC SOLUTION FOR THE GRAVITY FORCE AND THE VALUE OF G By Morton

Gravity is electrostatic. This paper substantiates this claim by deriving, through basic electrostatic relationships, a simple equation for gravity forces that includes an expression for the gravity constant G in terms of electrostatic parameters. Applied to interaction between two separated sub-atomic particles in open space, the derivation of G results in a value that falls within the range o...

High resolution space quartz-flexure accelerometer based on capacitive sensing and electrostatic control technology.

High precision accelerometer plays an important role in space scientific and technical applications. A quartz-flexure accelerometer operating in low frequency range, having a resolution of better than 1 ng/Hz(1/2), has been designed based on advanced capacitive sensing and electrostatic control technologies. A high precision capacitance displacement transducer with a resolution of better than 2...

Electrostatic self-force in (2+1)-dimensional cosmological gravity

Point sources in (2+1)-dimensional gravity are conical singularities that modify the global curvature of the space giving rise to selfinteraction effects on classical fields. In this work we study the electrostatic self-interaction of a point charge in the presence of point masses in (2+1)-dimensional gravity with a cosmological constant Λ. Exact expressions are obtained for the self-force on t...
