A 2130-kg space station orbits Earth at an altitude of 455 km. Find the magnitude of the force with which the space station attracts Earth. The mass and mean radius of Earth are 5.98 × 1024 kg and 6370 km, respectively.

F =G•m1•m2/R²
the gravitational constant G =6.67•10⁻¹¹ N•m²/kg²,
R=h+R(Earth)= (455+6370)•10³ m
