A test tube in a centrifuge is pivoted so that it swings out horizontally as the machine builds up speed. If the bottom of the tube is 180.0 mm from the central spin axis, and if the machine hits 54000 rev/min, what would be the centripetal force exerted on a giant amoeba of mass 8.00E9 kg at the bottom of the tube?
