A person of mass LaTeX: 80\:kg\:80 k gis lying on the second floor of a building which is LaTeX: 20 \space m20 m above the ground. With how much force is the person pulling the Earth toward her? Following information may be helpful to you: LaTeX: g\:=\:9.8\:m/s^{2}g = 9.8 m / s 2 Gravitational constant, LaTeX: G = 6.67 \times 10^{-11} Nm^2/kg^2G = 6.67 × 10 − 11 N m 2 / k g 2 The Earth has a mass of approximately LaTeX: 6.0\:\times10^{24}\:kg6.0 × 10 24 k g. Approximate distance between Earth and the person is LaTeX: 6400\:km6400 k m. Please choose the best approximation from below.
