Two small (green) objects, each of mass m, are separated by a solid, massless rod of length L. They are located so that one of the objects is located at a distance of r away from the center of a uniform spherical planet with mass M (see figure). M r m L m Assume that mn is very small so that you can ignore the gravitational force between the two small (green) objects. Is the rod being compressed, stretched, or neither? If compressed/stretched, calculate the magnitude of this deformation force on the rod. If neither, explain clearly why. (15 points)
Planet 1 has mass M₁ and radius R₁. Planet 2 has mass M₂ and radius R2. The two planets are a distance of L apart, measured from surface to surface: An object is launched with some initial speed from the surface of Planet 1 directly towards Planet 2. For this problem, assume that Planets 1 and 2 are stationary. (20 points) (a) At what initial speed must the object be launched so that it reaches the surface of Planet 2 with zero speed? (b) Derive an inequality between M₁ and M₂ that represents when (a) can occur. (c) Show that, using your result in (b), if R₁ = R2, then M₁ must be greater than M₂.
