A laboratory centrifuge on earth makes n rpm (rev/min) and produces an acceleration of 5.50 g at its outer end.

What is the acceleration (in 's, i.e., acceleration divided by) at a point halfway out to the end?

This centrifuge is now used in a space capsule on the planet Mercury, where g mercury is 0.378 what it is on earth. How many (in terms of ) should it make to produce 7 g mercury at its outer end?
