Imagine a thin unbreakable wire, one end of which is tied to the surface of the Earth and the other end extending 35,000 kilometers straight up into space and attached to a counterweight that keeps the wire up. Assume further that the wire has a uniform mass of 1 gram per kilometer. What would be the force acting on the wire at the Earth's surface and at various positions along the length of the wire? What is the formula for calculating those forces? (Ignore air effects; let me know assumptions you make.)
