Gravity is inversely proportional to the square of the distance.
In English:
Your weight at the Earth's surface and your weight 850 miles above the Earth's surface decreases by a factor of
(4,750 / 3,900) ^ 2 =
1.483399080
So your weight would decrease by (your weight /
1.483399080
)
If you weigh 180 pounds, at 850 miles above the Earth your weight is
180 /
1.483399080
which equals
121.3429362515
pounds.
