Answer:

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 =#mw^2r#.

If we want the same gravitational acceleration as on planet Earth then the rotational speed #w=sqrt (a_R/r)#

Where #w# - radians /s
#a_R = 9.8 m/s^2#
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 #2pi# revolutions
