New Test of the Gravitational $1/r^2$ Law at Separations down to 52 $\mu$m

J. G. Lee, E. G. Adelberger, T. S. Cook +2

We tested the gravitational $1/r^2$ law using a stationary torsion-balance detector and a rotating attractor containing test bodies with both 18-fold and 120-fold azimuthal symmetr…
