Use ratios only to obtain the weight of a person at the following distances. Assume the person weighs 980 N on the surface of the earth.
a) Three times the distance from the center of the Earth
b) Seven times the distance from the center of the Earth
c) 128 000 km above the surface of the Earth
d) 4.5 times the distance from the center of the earth
I just need to know the equation to answer these questions. Thanks in advance.
