The rotational speed will vary depending on the radius of the object imparting the artificial gravitational field.
Explanation:
From the physics laws governing rotational and orbital motion, the centripetal Force =
If we want the same gravitational acceleration as on planet Earth then the rotational speed
Where
r - radius of the rotating object in metres.
To express the angular rotation in revolutions per sec we can use the relationship that 1 radian is equivalent to
