It is shown that even in the case of a negligibly small change in the gradient of the gravitational field of the mass source in the axial direction, the dependence of this gradient in the radial direction leads to a systematic error in Newton gravitational constant value. The magnitude of this error is calculated for two configurations of the field. For both configurations it was found that this error is larger than the inaccuracy predicted in the article by Jain et al. (Eur Phys J D 75:197, 2021). In addition, we found the geometry of the source mass, for which this systematic error disappears.
