Abstract
The error in calculating the gravitational constant using the differential equation of motion is estimated. It is shown that a preliminary calculation of the oscillation period of a torsion balance using the standard value of the gravitational constant G 0 and the oscillation period when the spherical attracting masses are fixed at the nearer of the two positions produces a reduction in the error in calculating G in each combination of positions.
