if you are in the center of earth what will be the gravitational effect?

Answer 1

If you were in the center of the earth, maybe in a small bubble, you would be completely weightless.

Answer 2

Gravity is directly proportional to mass and inversely proportional to the distance between the masses. If you were at the center of the earth ,assuming you could withstand the heat with an AC unit just slightly better than that found in a '67 Ford and the pressure, the mass surrounding you would be roughly equal in all directions therefore the combined gravitational pull of the mass would be a 0 vector. You'd be weightless. Gravity would increase towards the center of the earth as you moved towards the surface. The only thing I'm not certain of is whether or not gravity would be highest on the surface or at some point beneath the surface. Actually if you had total freedom of movement while in the center of the earth without friction, The gravity of the sun and moon and to a lesser extent the other planets would pull you out away from the center until you reached a point of equilibrium which would constantly change due to the orbit and rotation of the earth and moon and other planets. So I guess you wouldn't be totally weightless at the center but very close.
Yes the exerted pressure of the material would be great, but the gravitational pull would be net zero.

Answer 3

As you progress further into the center of the Earth, the force you feel due to gravity would decrease – assuming the Earth around you is of uniform density. Because of the decreased force around you it would also mean that you wouldn't weigh as much.

The reason is that the mass attracting you is inside a sphere, and is given by M = (4/3) * pi * (radius)3 * density

The force you feel is given by F = G * M * (your mass) / (radius)2

This means the net force is F = G * (4/3) * pi * radius * density * (your mass)

(pi=3.14159 and G = Newton's gravitational constant)

As you go further inside the Earth, the radius (of the Earth) is decreasing from your perspective/locale, so the force you feel would also be decreasing.

But this is only if the Earth is of uniform density (which in reality it isn't) so in actual practice, you'd need to find the actual gravitational center precisely if one were to try to prove this in the real world.

But bottom line – you would weigh less standing in the center of Earth's core.

Answer 4

Theoretically, gravitational force becomes infinitely large as you approach the center. If you were a point mass, nothing would happen, you would just stay there. Assuming that the center will coincide with the center of your body, your body will be crushed by the immense gravitational force.

Answer 5

If the earth were truly symmetrical, the gravitational field at the exact center would be zero. The attraction of gravity in any direction is canceled out by and equal and opposite attraction in the opposite direction.

Answer 6

Gravity is force of attraction between two masses.

At the center of earth, since in all directions there are masses,almost equally distributed, the forces in all directins will be the same and pullong the point out ward. The net force is zeroi

Answer 7

the geometrical center of the earth may or may not be the center of gravity of the earth(as we dont know the distribution of mass). so u might be weightless and under great pressure if u r at CG. and u might be feeling weight and a little less pressure if u r at geometrical centre and not the CG of the earth.

Answer 8

hmm either you would become the center of the earth and get crushed into oblivion by the rest of the earth compacting down on you or the rest of the matter of the planet earth would be pulling you from every side perhaps tearing you apart

Answer 9

there is magma in the center on the earth for a reason... the gravitational pull in enough to heat up the earth to its melting point

in short: I dont know what would kill you first, but you would die!

Answer 10

The "effect" of gravity would be the very same as anywhere else in the universe.. The "pressure" would be increased.

And you would not be the size of a pin point... The pressure isn't that great. The other answerer was thinking of a black hole I bet..
