F = GMm R² M is the mass of the Earth m is the mass of the object R is the radius of the earth =6400km(given)
When object is kept on surface.W=F=GMm= 20 N R² When object is lifted to a certain height=R' = R+h = 2R h = R = 6400 kmNow we have weight of the object is
W' = F' = GMm (2R)² W' = (1/4).(GMm) R² =W 4Now the weight of the object will beweight=20 4W=5N
