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 your
position is there. You're only affected by the mass of the smaller sphere INSIDE your position, as if you were
on 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=mg
and gravity at center of earth is zero(g=0)
so weight is zero
What else can I help you with?
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 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.
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 is the value of 'g' at center of earth?
The value of acceleration due to gravity 'g' at the center of the Earth is theoretically zero because the mass of the Earth surrounds an object equally in all directions, resulting in a net gravitational force of zero at the center.
At what height from the earth the weight of an object become half of the weight on earth?
The weight of an object becomes half at a height where the gravitational force is half of the force on Earth, about 3,578 km above Earth's surface. At this height, the object and Earth are attracted with equal and opposite force.
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.

Weight of an object will be minimum when it is placed at?
weight of an object is minimum when it is placed at the center of the earth because when an object is in the center ,it experiences gravitational pull from all the sides.thus the net weight of an object remains to be zero. +++ Possibly, but given that the centre of the Earth is unreachable and a ball of metal anyway, a more useful and achievable location for weightlessness is in Space!
What is weight of the body at the center of the earth?
Zero

If a hole is drilled to the center of the earth and a stone whose mass is 1 kilogram at the surface of the earth is dropped into it then what is the weight at the center of the earth?
The weight of an object is its mass times the acceleration of gravity. The acceleration of gravity at the center of the Earth is zero. A 1 kg mass at the center of the Earth still has a mass of 1 kg, but the force of attraction between the 1kg mass and all the other mass around it will add up to zero.
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........
What is the value of 'g' at center of earth?
The value of acceleration due to gravity 'g' at the center of the Earth is theoretically zero because the mass of the Earth surrounds an object equally in all directions, resulting in a net gravitational force of zero at the center.
Where on earth would the weight of a body be zero?
w=mg gravity is zero at centre of earth then g=0 and w=m(0) =0 so weight is zero
At what height from the earth the weight of an object become half of the weight on earth?
The weight of an object becomes half at a height where the gravitational force is half of the force on Earth, about 3,578 km above Earth's surface. At this height, the object and Earth are attracted with equal and opposite force.
Does weight act towards the centre of the earth?
Yes, at the center it becomes zero.
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.
