Question
At a certain distance from the center of the Earth, a 4.00-kg object has a weight of 1.95 N. Calculate this distance.
Answers

Weight = m•g = G•m•M/(R + h)^2,
W=G•m•M/(R + h)^2,
where
G =6.67300•10^-11 m^3•kg^-1• s^-2
Earth mass M = 5.9742 • 10^24 kg
Earth radius R = 6.384•10^6 m
Solve for "h"
W=G•m•M/(R + h)^2,
where
G =6.67300•10^-11 m^3•kg^-1• s^-2
Earth mass M = 5.9742 • 10^24 kg
Earth radius R = 6.384•10^6 m
Solve for "h"
