1. The problem statement, all variables and given/known data A spaceship in outerspace has a donut shaped with a 500 m outer radius. The inhabitants stand with their heads towards the center and their feet on an outside rim. Over what time interval with the spaceship have to complete one rotation on its axis to make a bathroom scale have the same reading for the person in space as when on Earth's surface? 2. Relevant equations Possibly G*m1*m2/r^2 G= 6.67*10^-11 N*m^2 Or 4*pi^2*R/ T^2 3. The attempt at a solution Honestly I'm completely lost here. I'm not sure which formula to use to be able to solve for this.
