AnalysisThe torsional pendulum was found to have a rotation of 0.102 rad per Newton of force acting on each of the barbell masses. The calibrated response of the torsional pendulum was used to de-termine the force producing the measured angular displacement of the pendulum for 4 different combinations of test masses and test mass positions. When m1m2/r2is plotted versus the meas-ured force for each case the slope of the best-Ft line is G. G can be expressed as G=Fm1m2/r2( )with uncertainty δG=GFF2+m1m12+m2m22+2rr2and evaluates to 0.9x10
