1. The problem statement, all variables and given/known data A laboratory centrifuge on earth makes n rpm (rev/min) and produces an acceleration of 3.70 g at its outer end. a.) What is the acceleration g's at a point halfway out to the end? 2. Relevant equations a = (V^2)/R 3. The attempt at a solution I really don't know what to do. I thought that if you divide the radius by 2, the acceleration would double, according to the equation. That doesn't seem to be the case since the answer 7.40 is incorrect. Any help would be greatly appreciated.
