A 10 kg object sits on the surface of the Earth.
1. Calculate the magnitude of the gravitational force the Earth pulls on the 10 kg object.
|Force Earth on Object| = (Newtons)
2. A 10 kg object sits on the surface of the Earth. Assume the Earth has a mass of 6.4 x 10^24 kg and a radius of 6.4 x 10^6 m. What is the gravitational force that the object exerts on the Earth?
|F-object on Earth| = (Newtons)
