CP An interesting, though highly impractical example of oscillation is the motion of an object dropped down a hole that extends from one side of the earth, through its center, to the other side. With the assumption (not realistic) that the earth is a sphere of uniform density, prove that the motion is simple harmonic and find the period. ( Note: The gravitational force on the object as a function of the object’s distance r from the center of the earth was derived in Example 13.10 (Section 13.6). The motion is simple harmonic if the acceleration a x and the displacement from equilibrium x are related by Eq. (14.8), and the period is then T = 2 π / ω .)
