Acceleration due to gravity is 9.8 m/s on the surface of Earth, and at orbits 200 miles above the surface of Earth, where the space shuttle orbits, the acceleration is O zero; astronauts feel weightless O undetermined, because it depends on the mass of the spacecraft or satellite. O less than 9.8 m/s2. greater than 9.8 m/s2 . exactly 9.8 m/s2-same as on the surface of Earth. QUESTION 24 A 29,000 kg spaceship wants to orbit a tiny black hole at a height of 10,000 m. The force of gravity of the black hole on the spaceship is 680,000 N. What is the mass of the black hole? Use G=6.67x 10-11 Nm2 ko2
