Astronauts on the space station orbiting earth are said to be in "zero gravity". find the gravitational acceleration at the space station that is 350 km above the surface of earth (in term of g0 − gravitation acceleration near earth's surface). assume that radius of earth is 6370 km.

Given: Mass of Earth Me = 5.98 x 10²⁴ Kg  

           G = 6.67 X 10⁻¹¹ N.m²/Kg²

      Radius of Earth re = 6, 370 Km + 350 Km( Height or altitude of Satellite)

      (Radius total) re = 6,720 Km convert to meter re = 6.72 x 10⁷ m

Required: gravity g = ?

Formula:  g = GMe/re²

                g = (6.67 x 10⁻¹¹ N.m²/Kg²)(5.98 x 10²⁴ Kg)/(6.72 x 10⁷ m)²

                g = 0.09 m/s²
