Is it possible for an object to have its center of gravity where "no mass" exists?

Answer 1

It is possible if the object is hollow and the hollow area is in a perfect vacuum. That would be the only way you would have "no mass" to exist where it's center of gravity would be located.

Answer 2

Without a mass, a centre of gravity cannot exist, since gravitational force has 'no mass' to act upon".

Oh, it is clear that I understood your question a little differently. If you meant what the others implied, yes, all hollow bodies have their center of gravity in a region where physical mass does not exist. The mass of the body is 'effectively' concentrated there (that means for the purpose of the gravitational effects).

Answer 3

Yes. The center of gravity of a hollow sphere would still be the center of the sphere, despite the fact that there is no mass in the (hollow) center. The center is still the focus of the bodies mass.

Answer 4

Yes it is possible and for a body to have center of gravity at a point where no mass exists......
Consider the following points first
1.Although center of mass and center of gravity are two different point for an irregular body these points coincide for a symmetrical body like a uniform sphere..
2.Now for symmetrical bodies this center of gravity is at the geometric center of the body..Now a hollow uniform sphere has no mass in it and yet it has a center of gravity at its center..
This is undisputable and True in Physics...

Answer 5

it is possible that the center of gravity of a object is somewhere that there is no mass there, for example imagine a circle of outer radius r and inner radius of R and the outer part of this circle(area between two circles) has a homogeneous mass the center of gravity of this object is in the center of these circles while there is no mass there

Answer 6

Like a ring?

Answer 7

a dipole would fit that description I think
