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 145.0 mm from the central spin axis, and if the machine hits 46500 rev/min, what would be the centripetal force exerted on a giant amoeba of mass 1.10E-8 kg at the bottom of the tube?
