<p>How would you determine the centrifugal force that acts on an astronaut with mass 200kg that is standing on the surface of the moon?? </p>
<p>(hint: centrifugal force=difference between the gravity and normal forces acting on astronaut)</p>
<p>This is a badly worded question! It depends on where you stand on the moon- if you stood at one of the poles it would be zero, while if you stood on the equator it would be mv^2/r (provided by gravitational force).</p>
