question 2 please 

Use the following information for problems (1) and (2): The figure on the right is a graph of the energy of a system of a planet interacting with a star. The gravitational potential energy U, is shown as the thick curve, and plotted along the vertical axis are various values of K + Ug K + Ug A + r1 12 r, from star to planet 1. Suppose that K+ Ug of the system is A. Which of the following statements are true? Explain your reasoning. a. The potential energy of the system decreases as the planet moves from r₁ to 1₂. b. When the two bodies are separated by amount r2, the kinetic energy of the system is (A – B). The system is a bound system; the planet can never escape. d. The planet will escape. c. f. e. When the separation between the two bodies is r2, the kinetic energy of the system is (B − C). The kinetic energy of the system is greater when the distance between the star and planet is r₁ than when the distance between the two bodies is r2. 2. Suppose that K+ Ug of the system is B.
