In Larry Niven’s science fiction novel
Ringworld, a ring of material of radius
1.54 × 1011 m rotates about a star with a
rotational speed of 1.5 × 106 m/s. The inhabitants of this ring world experience a normal
contact force ~n. Acting alone, this normal
force would produce an inward acceleration of
9.67 m/s^2
. Additionally, the star at the center of the ring exerts a gravitational force on
the ring and its inhabitants.
What is the total centripetal acceleration of
the inhabitants? The universal gravitational
constant is 6.67259 × 10−11 N · m^2/kg^2
Answer in units of m/s^2
