g =8.71 N/kg.
h = 150 000 m=1.5•10^5 m
R= 8.71•10^7 m.
(a) g = G•M/(R+h)².
M = gR²/G,
where the gravitational constant G =6.67•10^-11 N•m²/kg²,
(b) gₒ = G•M/R².
(c) m•gₒ.
h = 150 000 m=1.5•10^5 m
R= 8.71•10^7 m.
(a) g = G•M/(R+h)².
M = gR²/G,
where the gravitational constant G =6.67•10^-11 N•m²/kg²,
(b) gₒ = G•M/R².
(c) m•gₒ.
