4. You whirl a tennis ball attached to string (at constant speed) in a vertical circle. Which of the following statements is true? (1) The tension in the string is minimum at the top of the circle. (2) This is not an example of uniform circular motion. (3) The magnitude of the net force on the ball is maximum at the bottom of the circle. (4) None of the other options are correct. The magnitude of the ball's acceleration varies with its position along the circle. the gravitational constant G, determine the speed of Earth's orbital motion vg. 2GMS 5. The Earth, with mass mg, orbits the sun, with mass Ms, with a period T, at a radius rg. Using this information, and GMşmg 4nT (4) vg = (5) vg= Mgmg 2nGT (2) vE (3) ve = Gmg (1) vg = 4.
