Popis:	We discuss two null experiments designed to test the inverse-square law of gravity in the critical range between and with higher precision than earlier work. To do so, we have devised a torsion pendulum detector whose mass distribution is specifically configured to provide high-sensitivity detection of a uniquely non-Newtonian derivative of the potential (the horizontal derivative of the Laplacian), rather than looking for a small deviation from the expected power-law dependence on distance of a Newtonian field derivative. This method provides a stronger null test of the gravitational inverse-square law force because it is less sensitive to imperfections in the source mass. We discuss the design of these experiments and estimate their performance relative to currently established experimental limits on inverse-square law violation.
