What is the acceleration due to gravity g' on the space shuttle in orbit, 200km above the surface of the earth? The gravitational constant is 6.67 x 10^-11 N*m^2/kg^2, the radius of the Earth is 6.4 x 10^6 m, the mass of the Earth is 6 x 10^24 kg, and the acceleration due to gravity is 9.8 m/s^2. Answer in units of m/s^2. Also what is the ratio of g' to the value of g on the surface of the Earth?
