how far from the center of the earth would a person with a weight of 469N on earth have to be to have a weight off 55.4N?

1 answer

weight decreases as the square of distance, so since the weight ratio is

55.4/469 = 0.1181

the distance ratio will have to be

1/√.1181 = 2.909

so, what's 2.909 times the earth's radius?
