Abstract
An analysis is made of the influence of corrections caused by gradients of the gravitational fields of closely positioned concentrated masses on the results of calculating the gravitational constant. A correction in the form of the product of the difference of the squares of the oscillations amplitudes with an experimentally determined coefficient should be added to the period for the smaller amplitude and subtracted from the period for the larger amplitude. It is shown that the systematic error is reduced by introducing this correction.
