Question: (a) Taking the potential energy to be zero at infinite separation, find the potential energy of a 100-kg object at the surface of the earth.

(a) Taking the potential energy to be zero at infinite separation, find the potential energy of a 100-kg object at the surface of the earth. (Use 6.37 x 10⁶ m for the earth’s radius.)

(b) Find the potential energy of the same object at a height above the earth’s surface equal to the earth’s radius.
