Man in a rotating spaceship

A spaceman, who weighs 75 kg on the Earth, is in a room of a spaceship that is rotating around the axis through the centre of the spaceship with angular speed $\displaystyle \omega = 0,5 rad/s$. The spaceman is on a weight scale and he sees that he weighs 70 kg. At what distance he is from the axe of rotation?
How can I deal with this problem? I don't know what formula use!

Basic formula (as often the case) is: $\displaystyle F = m a$

For a rotating frame with constant angular velocity the value of acceleration is $\displaystyle a =r \omega^2 $. You have values for m, F, and $\displaystyle \omega$, so you should be able to solve for r.
