masses and each end of the barbell causes a rotation of the torsional pendulum that can be meas- ured to determine the gravitational force. For various mass test-masses and test-mass–barbell separations the gravitational force is measured and the value. The value of G is determined from the slope of a plot of force versus m 1 m 2 /r 2 12 .
