How does gravity work in toroidal masses?

Even when spinning, a toroidal object would have a very specific gravity; objects on top of or inside the spinning object would follow Newtonian physical laws of motion, but the gravitational force itself would remain constant.

In toroidal masses, such as a donut-shaped object, gravity still operates in accordance with Newton's law of universal gravitation, which states that every particle attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. The gravitational force experienced by an object within a toroidal mass would depend on its distance from the center of the mass and the distribution of mass within the torus. However, in practice, the gravitational effects of toroidal masses are generally negligible compared to more conventional spherical masses.
