Question 8 • Physics
For a circular orbit, gravity supplies the centripetal force, so the orbital radius from Earth’s center is r = GM/v². Using the given values gives r = (6.67 × 10⁻¹¹)(6 × 10²⁴)/(5000)² = 16,008,000 m. The distance above Earth’s surface is 16,008,000 − 6,400,000 = 9,608,000 m, so the answer is C, 9,608,000 m.
