w=mg
gravity is zero at centre of earth
then g=0
and w=m(0)
=0
so weight is zero

∙ 13y agoIt doesn't. An object's weight is equal to its mass times the value of its rate of acceleration towards the nearest large object (more or less) due to the gravitational pull of that object. This rate of acceleration decreases as one moves away from the large object (for example, the Earth). In orbit around the Earth, one's distance from the Earth is obviously larger than if one is, say, a few feet above the surface. So, in orbit, one's weight is less than it would be on the Earth's surface. But it is not zero.
An astronaut "floating" in space does have zero apparentweight. But that's a different matter.

∙ 12y agoThe very center of the Earth is the only place where you would have no weight. However, strictly speaking, that is not a place on the Earth but in it. More practically speaking, because of the pressure, temperature and the vast quantity of rock between where we live and the center of the earth, you could never get there - and if you could you would not be alive when you did.

Is the weight of a body constant at all places on the earth?
The weight of a person is not constant at all places on the Earth. The weight becomes zero at the center of the earth or far away from the Earth.
Person sitting in an artificial satellite of the earth have?
... a feeling as if his weight is zero, because he is constantly falling around the Earth in the satellite's orbit..
On a distant planet the acceleration due to gravity is less than it is on earth Would you float more easily in water on this planet than on earth?
Both your weight and the water pressure would decrease, so it would be the same as on earth. Floating is nothing to do with the size of g, provided it isn't zero, or water pressure. If your density is less than that of water, you will float.
What would happen if the earth did not have the force of gravity?
If the force of gravity of Earth were to drop to zero, to put it in simple terms: Firstly, the whole atmosphere would leave Earth. Meaning all living things would most probably die as many of us can't live without air. Secondly, the moon would most probably float off to space. Without Earth's gravity, it is highly possibly we would never see the moon again. Either that, or the moon's gravity on its own could hold and it would merely be further away from Earth than usual. Thirdly, those not clutching onto something would definitely float off to space as well. People who wants to be lighter would be happier however, as without gravity, everyone's weight is reduced to zero kg, zero grams, zero pounds, etc.
What happens to an objects mass weight and volume when taken into space?
Mass: Does not change Weight: The weight will be zero, if you are not standing on a large massive body (like the moon). When in orbit you are actually in continuous freefall around the planet with a sufficient tangential velocity component. Volume: If the object is filled with gas from the earth's lower atmosphere the gas will exert this pressure on the sides of the object, prehaps causing the object to explode.
Where on the earth would the weight of body be zero why?
on the centre of the earth.
What is weight of the body at the center of the earth?
Zero
What will happen to mass and weight of a body on earth if suddenly gravitational attraction of the earth disappeared?
Your mass would be unaffected, it is simply to do with the atoms in your body. Your weight would be reduced to zero as that is simply how much your body is affected by gravity.
Is the weight of a body constant at all places on the earth?
The weight of a person is not constant at all places on the Earth. The weight becomes zero at the center of the earth or far away from the Earth.
What would be the weight in kilograms of a 50 kg body?
The weight of a body depends upon the force of gravity acting upon that body. A 50 kg body will have a weight that is 50 times that of a 1 kg mass. The weight of the body will be different on earth, on the moon and in deep space (zero).
What is the value of Earth's gravitational field at the center of the Earth?
In the cavity at the center of the Earth, your weight would be zero, because you would be pulled equally by gravity in all directions. - The gravitational field of Earth at its center is zero.
Can a body have zero mass and zero weight?
no
At what height from the earth the weight of an object become half of the weight on earth?
zero
As you get farther away from the earth what will happen to your weight?
It will steadily decrease as you move farther from the Earth's center of gravity. Eventually one's "Earth weight" can reach zero when the gravity of another body, such as the Moon or Sun, completely counteracts it. *In orbit, or freefall, measured weight is zero. In outer space, objects are always in "microgravity" having imperceptible weight, unless they approach close to another large body.
What happens to the mass of a body when it is at the center of the earth?
Assuming that you could get the mass there and intact, the mass of the body would not change. Its weight, however would be zero. Depending on the matter used, the volume might be considerably reduced due to pressure.
Where does a body have least weight equator or earth centre?
In the middle of the earth is where an object has the lightest weight. The weight is zero. The reason is that the mass of the object is pulled equally in all directions so all the forces cancel out.
What is weight of earth?
AS WE KNOW, that there is the force of gravity at the center of Earth, if every part or portion of earth has its weight then net weight of the earth will be zero........
