**Damon**, Friday, January 25, 2013 at 4:57pm-The distribution of mass in the earth is spherically symmetric.

Yes, if all the mass were under Paris, g would be very high there.

-The density of the earth is the same everywhere.

No, all the mass could be at the center

-The earth's interior is solid everywhere.

No, again all the mass could be at center

-The orbit of the earth is circular and not elliptical.

Not relevant

Yes

-The object is at the earth's surface.

Yes
