We give analytic expressions for the gravitational inner spherical multipolemoments, q_{lm} with l <= 5, for 11 elementary solid shapes. These moments, inconjunction with their known rotational and translational properties, can beused to calculate precisely the moments of complex objects that may beassembled from the elementary shapes. We also give an analytic expression forthe gravitational force between two rectangular solids at arbitraryseparations. These expressions are useful for computing the gravitationalproperties of complex instruments, such as those used in equivalence principletests, and in the gravitational balancing of drag-free spacecraft.Comment: 12 pages, as published in CQ
