Abstract
Motivated by extra dimensions theories that predict new effects, a proposal of experimental searching for the deviation from Newtonian gravitational Inverse-Square Law (ISL) in short-range is presented, which is based on an electrostatic space accelerometer to test ISL at the separation close to 10 μm. Several systematic uncertainties, including spurious force due to the Casimir force and electric force, and various sources of random uncertainty due to patch field and detector noise are discussed. Our analysis suggests that on microgravity, drag-free satellite, the proposed experiment will improve the current constraint on the possible new forces by 3 to 4 orders of magnitude.
