m = 1 kg, M=6*10^24 kg&amp;lt;, R=6.4×10^6 m  F  =  G            M      ×      m              R      2        G  =  6.67  ×      10          −      11        N      m    2        /    k      g    2   is the universal gravitational constant. So,   F  =  G            M      ×      m              R      2        =            6.67      ×              10                  −          11                    ×      6      ×              10                  24                    ×      1              (      6.4      ×              10        6                    )        2              =  9.77  N  ≈  9.8  N
