How far from the earth’s surface would a 72.1kg person experience a force of1.6 Newtons?

2 answers

F = GMm/r^2
Look up G and M, and then plug in the numbers
The radius of the earth is 6356 km
Since F = GMm/r^2
Fr^2 = GMm and is constant, you want r such that
(1.6*r^2) = (72.1*9.8*6356^2)
Find r, then you want r-6356
