What will be our Weight at center of earth if it was hollow sphere?

Theoretically, Zero. The gravitational pull of the earth on you (which is the definition of weight), whether the earth is solid or hollow, is the same in all directions because it is spherically symmetrical. These forces cancel each other out, leaving you with zero net weight. In real life, the earth is not a perfect sphere, but this model describes the situation adequately.

Why is the weight of an object zero at the center of the earth?
The gravitational attraction is not by anything special in the center of the Earth; instead, it is the sum of the attraction by every individual atom.For an object in the center of the Earth, the pull in one direction will be exactly compensated by the pull in another direction.So it turns out that if you're anywhere inside a solid sphere, it acts as if none of the mass OUTSIDE of yourposition is there. You're only affected by the mass of the smaller sphere INSIDE your position, as if you wereon its surface, and the 'shell' outside of your position had gone away.The weight is zero at the center of the earth. since F= G M.m / 2 d at the center of the earth the distance is zero from the center thus no force is imaginable. a more profound explanation is that at the center you are being puled by every particle from all sides with equal forces, the net force is logically zero.since weight=mgand gravity at center of earth is zero(g=0)so weight is zero
What is the inercore?
A dense sphere of solid iron and nickel at the center of earth.
Why the acceleration due to gravity depends on where on the earth you are?
Because the Earth is not a perfect sphere, so at different locations, you can be slightly nearer or slightly farther from the Earth's center.
Weight of an object will be minimum when placed at?
The weight of an object will be minimum at high point like mountain. This is because weight depends on acceleration due to gravity and acceleration due to gravity is inversely proportional to the square of distance from center of earth to the object. As high places like mountain is far from earth center, there is minimun weight. But at the center of earth the weight becomes null as gravity pull takes place in all direction from the center.
What will be the weight of a body it is raised above the earth equal to its radius?
Since the distance from the Earth's center will be doubled, the force or weight will be reduced by a factor of 4.
According to the ancients the stars traveled around Earth on the transparent hollow?
celestial sphere
What is the weight of the body at the center of the earth?
In theory, at the center of the Earth you would have no weight.
What happens to your weight as you get farther from the center of earth?
As you get farther from the center of Earth, your weight willDECREASE
Center of mass of Earth's atmosphere?
Assuming that the Earth's atmosphere is a perfect sphere, then the atmosphere's center of mass will be at the point equidistant between Earth's poles (i.e. the center of the Earth!).
Is our Earth hollow in the center?
Many theorists believe that the entrance to the Earth hollow is located at 87.7 degrees North latitude and at 87.7 degrees South latitude which is the location of the North and South Pole. These polar openings lead directly to the Earth's core which has led these theorists to believe that the Earth's hollow is in the center of the Earth's core.

Celestial Sphere is modeled on what major misconception?
that the earth is the center of the universe
What is Dense sphere of solid iron and nickel at the center of the earth?
core
What is the inercore?
A dense sphere of solid iron and nickel at the center of earth.
What is the gravitational potential energy at the center of the earth?
Ideally, if the earth were a perfect sphere, the gravitational potential energy would be zero. In the center of a sphere all other points within the sphere have an equal and opposite counterpoint. They work to cancel each other out. However, the earth is not a perfect sphere so there would likely be a gravitational pull towards the area with the greatest mass.
What is the dense sphere or solid iron and nickel at the center of the earth?
inner core
What is the sphere of very hot metal at the center of the earth?
this is called the mantel or POP.
