K. Kuroda et al., EXPECTED IMPROVEMENT IN THE DETERMINATION OF G USING AN X-PENDULUM, International journal of modern physics A, 12(11), 1997, pp. 1967-1974
We propose the application of a new technique, the X pendulum, to dete
rmine the Newtonian gravitational constant G. We evaluate the likely e
xperimental errors for configurations realizable with existing technol
ogies and show that improvement of the accuracy by an order of magnitu
de or more is possible.
