7,000 km
on the surfaceNote:Since the earth's composition is not homogeneous, the gravitational acceleration onthe surface is probably less than what it is some small distance below the surface,but it's certainly greater than at the center.
That's the Earth's radius. It's about 6378 kilometers at the equator. That's 3963 miles.
Infinity
That would have to be at a radius that is sqrt(26) = 5.1 times the Earth's physical radius, or about 32,486 kilometers (20,186 miles) from the center.
Yes.
i hate this home work
You would have to double your distance from the center of the earth, or about 4,000 miles off the surface.
vent a+
The equator.
No
about 6370km from the earths surface,convert now to feet
it sucks
