F = GMm/ R^2
M is the mass of the Earth m is the mass of the object
R is the radius of the earth =6400km
When object is kept on surface.
W=
F=
GMm/R^2
= 100 N
When object is lifted to a certain height=R' = R+h = 2R
h = R = 1600 km
Now we have weight of the object is
W' = F' = GMm/(8000)^2
W' = 0.64W
Now the weight of the object will be
weight= 0.64 × 100
W = 64 N
hope this helps you out!
