Which location on Earth has the strongest deviation from the vertical due to gravity?
So, I've recently learned about the Schiehallion experiment, performed in 1774, where scientists detected the deviation from the vertical of a plumb due to the gravitational attraction of a single ...

Would a body have any residual velocity if launched at escape velocity from the Earth's surface?
A body is lanuched at escape velocity from the Earth's surface i.e 11.2 km/s ,what would be it's velocity outside the Earth's gravitational field?
I guess it would be zero but there's another problem ...
