What is the acceleration due to gravity at 7220km above the Earth's surface? Take the radius of the Earth to be 6.37e6m and the mass of the Earth to be 5.972e24kg.

  • Physics HELP!! -

    g=G•M/(R+h)²,
    the gravitational constant
    G =6.67•10^-11 N•m²/kg²,
    Earth’s mass is M = 5.972•10^24 kg,
    Earth’s radius is R = 6.37 •10^6 m.
    h=7220000 m
