Where on the earth would the weight of body be zero why?

on the centre of the earth.


Why is the weight of a body zero at the center of the earth?

At the centre of the Earth, or any body for that matter, the mass of the Earth is centralised at the centre, At the centre of the earth there is no weight attributable to the earth's mass. But there is weight (a force) attributable to the sun's mass, neatly balanced out by the speed of the earth in its circular orbit. So the weight is mv2/r instead of mg (m= a mass placed at the centre, v=velocity in orbit, r= distance to sun). If the earth slowed to a stop, it, and everything at its centre would accelerate towards the sun. If somehow you could nail the earth down so it didn't fall in, that weight would be measureable with a spring balance. Ignoring galactic and intergalactic forces. I guess that's sophistry really.

Does weight act towards the centre of the earth?

Yes, at the center it becomes zero.


What change in weight occurs going towards the centre of the Earth?

Gravity... :D


Why does a body lose weight at the centre of the earth?

In the center of the Earth gravity is equal at every side causing you to be "weightless".


What will be the weight of an object at centre of earth if it is 10kg on surface of earth?

The weight of the object at the center of the Earth would be zero. This is because at the center of the Earth, the gravitational forces from all directions cancel each other out.


What is the definition of weight as it is used in science and technology?

Weight is the FORCE by which Earth PULL any body towards it centre of gravity.


Why a men bow himself while carrying heavy lod on his back?

Every object on the Earth is governed by a force called Gravity. But regardless to the shape of the object, every oject has a 'centre of Gravity'. To, attain the position of stability the centre of gravity and the centre of mass of that object should be on same vertical line (perpendicular to earth). So, when man lift the heavy weight it total mass increased and and the centre of mass deviates from the centre of gravity of that man (man+ weight), so to maintain the stability man bow down to bring back its centre of mass with its centre of gravity. and in this way he can walk/stand with the load, otherwise we will fall back with its load.


What is the body weight in centre of the earth?

The body weight at the center of the Earth would be zero because the mass surrounding you in all directions would create a gravitational pull in every direction, effectively cancelling out any perceived weight.


What is the centre of the earth like?

The centre of the earth is very hot.


Is there any difference in weight on earth with change in position of a man?

Yes there is. Weight it is affected by distance form the centre of the earth. Because the world is not a perfect sphere, a man is further from the centre of the earth when he is nearer the equator and so lighter. He is also lighter when he is at a greater altitude.Weight is also affected by localised masses. If there is a really large lump of metal underneath the man, he will be heavier. Aquifers also affect the weight.
