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.
g-forces are not caused by gravity. yes, g-force can be experienced in zero-g. just ride a centrifuge.
No.
For any object that has mass, there is no place on the surface of the Earth where the gravitational force on the object is 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.
Zero gravity is not a question of height or altitude, its a question about motion. You can experience something close to zero G on a roller coaster, air plane, falling elevator and sky diving. All of these involve MOTION. Just as the space station, or space ship is falling around a planet (called orbit) it is the falling, not the distance above the planet that creates zero gravity.
Zero.
Zero.
i think value of g becomes zero
There will be no gravity. Objects will start floating.
No, at the center of the Earth, it would be zero. That's because the gravitation of different parts of the Earth, in different directions, would cancel.
well he is somewhere in the manga of the zero g. Look on fanpop for the picture

The most meaningful answer is zero G. You, the space-station and everything in it are in free-fall towards Earth. All are 'weightless' (but not massless).
Zero-g surgery probably isn't economically feasible at present. Sustained zero-g means in orbit. That costs a ton. Simulated zero-g like is effected in a plane that descends at a rate equal to the gravimetric constant (g), but it doesn't last long. Plus, is zero-g surgery safe? That is an open question.
A system has a G equal to zero means it has reached equilibrium .
Soon.
g = 9.81 m/s2 = 32.2 ft/s2the above is a wrong answer. that's g on the surface of the earth.g varies and actually decreases as we move up or down the surface. g at the centre of any spherical body due to it's own mass is 0. So g at the centre of earth is zero.
