An astronaut standing on the surface of the moon experiences a gravitational force of attraction of 160 N. He then moves away from the surface of the moon to an altitude where gravitational force is 40 N.
a) How far away from the centre of the moon is this new location in terms of the radius of the moon?
I know that Fg is proportional to 1/r^2
I dont know how to figure it out, can anyone point me in the right direction?
Thanks.
