The weight w (in N) of an object h meters above the surface of Earth is w r 2 w (r h) 2 , where r is the radius of Earth and w 0 is the weight of the object at sea level Given that r 6380 km, if an object weighs 200 N at sea level, for what altitudes is its weight less than 100 N

Question: The weight w (in N) of an object h meters above the surface of Earth is w = r 2 w (r + h) 2

The weight w (in N) of an object h meters above the surface of Earth is w = r²w (r + h)², where r is the radius of Earth and w₀ is the weight of the object at sea level. Given that r = 6380 km, if an object weighs 200 N at sea level, for what altitudes is its weight less than 100 N?
