Assuming the ball is a perfect sphere of uniform density, and is suspended from a massless string, the centre of gravity is in the centre of the ball.
Teh force of gravity is measured form the center of gravity, thus the center of gravity of the object is appropriately the center of the force. The center of the sphere is also the center of gravity of the sphere.
The center of gravity for a spherical object is located at its geometric center, which is also the center of the sphere. This point is equidistant from all points on the surface of the sphere, making it the point where the force of gravity can be considered to act.
The center of gravity of a sphere full of water that is leaking will gradually shift as the water leaks out. Initially, the center of gravity will be at the geometric center of the sphere. However, as water leaks out, the center of gravity will move towards the direction of the leak due to the changing distribution of mass within the sphere. The final position of the center of gravity will depend on the rate of leakage and the amount of water remaining in the sphere.
That all depends on the shape of the object and how its mass is distributed. The center of gravity of a solid sphere is at the center of the solid sphere. The center of gravity of a solid cube is at the center of the solid cube. The Earth's center of gravity is at the center of the Earth, and there's certainly plenty of mass there. But the center of gravity of a ring is at the center of the ring ... an open space where the finger goes.
The effect of gravity inside a solid sphere is that it pulls objects towards the center of the sphere, with the force of gravity decreasing as you move towards the surface. This is because the mass of the sphere is concentrated at the center, creating a gravitational pull towards that point.
The center of gravity for a spherical object is located at the exact center of the sphere. This point is equidistant from all points on the surface of the sphere, making it the point where the force of gravity can be considered to act on the object.
The location of an object's center of gravity depends on the object's shape, and on how its mass is distributed throughout its shape, but not on its size. The center of gravity of a homogeneous sphere is at the center of the sphere, no matter whether the sphere's radius is 1 millimeter or 1 light year.
It is always different depending on the object. For example a female humans' center of gravity is in the hip. as a male humans' center of gravity is in the chest. But once you have found the center of gravity in an object the center of gravity should be the same in every object like it.
Uranus, like most astronomical bodies of its size, is a sphere due to gravity. The planet's own gravity pulls its material in towards its center, creating a spherical shape. Additionally, over time, collisions and pressure from within also contribute to shaping it into a sphere.
The center of mass of a sphere is its geometric center.
It's an older term; nowadays the phrase "Center of mass" seems to be preferred. It's, basically, the mass-weighted center of a ... well, a thing. The center of a sphere of uniform density is easy to calculate; it's the geometric center of the sphere. For other shapes or for objects where the density is not the same throughout, it's more complicated.
Every planet has a center of gravity, anda sphere is the mostgravitationally stable shape for a planet to have.
