...placed in tube is harmonic? Assuming the earth to be of uniform density, drill a hole through the earth between any two points on the surface of the earth. Install a frictionless tube, and evacuate all the air. Show that the motion of a subway car placed in this tube is simple harmonic motion and evaluate the period of this motion. (Hint: use a gravitational equivalent of Gauss's Law.)
