Effects of gravity on a mass measured at sea level and atop a 5km mountain

A mass of 100kg weighs 980.6N at sea level. Estimate the weight of this body at the top of a mountain 5km high. Assume that the mean diameter of the earth is 12742km.

Solution Preview

Because weight at the earth surface (Wo) = GMe*m/Re^2
where, G = universal gravitational constant,
Me = ...
