Puzzle of the day from perplexus.info:Tethered satellites (Difficulty: 3 of 5)  Two identical spheres are connected by an elastic tether. The tether obeys Hooke's Law for ideal springs. At a particular moment in time, the tether is in a straight line, at its resting length, neither stretching nor contracting. This assembly is then placed into a circular orbit around the Earth, and oriented so that a line drawn from one sphere through the tether and the other sphere points directly at the Earth. Give a qualitative description of the motion of the two spheres relative to each other over time.
