if four horses with equal power are pulling one from opposite sides, it will not move. means net force would be zero. same is at center of earth. the mass of earth around center attracts equally to all sides( because geometrical center and center of mass are same). so net force is zero. On the other hand if you think of gravity as a force puling you into the centre of the earth then when you are at the center of the earth gravity must be zeero

What is the gravitational potential at the center of the earth?
The gravitational potential at the center of the Earth is zero because all the mass of the Earth is above this point, exerting gravitational force in all directions and creating a balanced potential field.
Where earth gravitationl force become zero?
Because there is no range limit on the gravitational force, the gravitational force of the earth is only zero in the exact centre of the earth, where it cancels itself out. Realistically, the force is so small outside the immediate vicinity of earth, that it may as well be zero.
How g becomes zero at the centre of earth?
At the center of a sphere, for every dot of mass attracting you toward it, there'sanother dot of mass at exactly the same distance from you in exactly the oppositedirection, attracting you toward it and canceling out the first one.
What is the value of null point where the value of gravitational force of earth equals the gravitational force of moon?
The null point, also known as the Lagrange point, where the gravitational force of Earth equals the gravitational force of the Moon is at a distance of about 56,000 kilometers (35,000 miles) from the center of the Earth, in the direction of the Moon. At this point, the forces are balanced, so an object placed there would experience zero net gravitational force from the Earth and Moon.
Why g is zero at the cetre of the earth?
At the center, for every particle of mass in the earth toward which you're gravitationally attracted, there's an equal particle with the same mass, located at the same distance from you in exactly the opposite direction, balancing out the force toward the first one. That statement assumes that the earth is a perfect sphere with the same distribution of mass in every direction from the center. The real earth is oddly shaped, lumpy and bumpy, so the acceleration of gravity wouldn't be exactly zero at the center.
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.
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.
What is the gravitational potential at the center of the earth?
The gravitational potential at the center of the Earth is zero because all the mass of the Earth is above this point, exerting gravitational force in all directions and creating a balanced potential field.

How do you create zero gravitational force on earth?
Gravitation can't be cancelled or shielded. You can have the appearance of zero gravitational force when you are in free fall. Without going into outer space, this can be maintained for a few seconds at most.
What will be time period of simple pendulum at the centre of the earth?
at the center of the earth, simple pendulmn has not any gravitational force(if we thought,the earth is an etended object) so at the center the gravitational acceleation is about 'zero' and that's why pendulumn's time period is 'infinite'.
On planet earth there is no centrifugal force at the?
At the center of the Earth, the centrifugal force is zero because all mass is evenly distributed around that point, resulting in a gravitational force that is balanced. As you move away from the center, both gravitational and centrifugal forces increase. At the surface of the Earth, the centrifugal force is present due to the rotation of the planet.
What is the force of gravitation between the earth and a body at the centre of earth?
The gravitational force between the earth and a body at the center of the earth would be 0 Newtons or 0 lbf. F=G (m1*m2)/r^2 r = zero if the center of the body is at the center of the earth
How much is the gravity at the center of the earth and in which direction is it pulling?
The gravity at the center of the Earth is zero because the mass around you causes gravity to be in equilibrium. It is pulling in all directions equally, resulting in a net zero gravitational force at the center.
How g becomes zero at the centre of earth?
At the center of a sphere, for every dot of mass attracting you toward it, there'sanother dot of mass at exactly the same distance from you in exactly the oppositedirection, attracting you toward it and canceling out the first one.
