I KNOW THIS MUCH----- confuesed what to plug in where. and what not to plug in. The weight is equal ‘mg”
On the Earth surface acceleration due to gravity is
the gravitational constant G =6.67•10^-11 N•m²/kg²,
Earth’s mass is M = 5.97•10^24 kg,
Earth’s radius is R = 6.378•10^6 m.
Let's find “g” at the height “h” . Distance between the mas “m” (the person) and the center of the Earth is 2R =>
In the "high" building mg1= mg/4
You are making this much too complicated.
This is right:
now what if to went to radius = 2R
mg = GmM/(2R)^2
new weight = 1/4 of original weight
That is what their HINT means.
