The mass of one planet in a distant galaxy is 0.58 that of the Earth's mass , and its radius is 0.57 that of the Earth's radius.
What is Fnew, the factor by which the man's weight is reduced if he were orbiting the planet at a distance of 3.5 Earth radii above the planet's surface? i.e., Weight(3.5 Earth radii above planet's surface) = Weight(at planet's surface)/Fnew
I know that the man is 82kg and weighs 1436.022N on the surface of the planet.
F= (M x m)/R^2
The Attempt at a Solution
I've tried doing .58/(.57+3.5)^2 times 82 and a few other things but I'm just not really sure how to solve this problem and it's been frustrating me for a few hours.
Thanks for the help!
