The centrifuge is a device in which a small container of material is rotated at a high speed on a circular path. Such a device is used in medical laboratories, for instance to cause the more less dense blood serum and collect at the bottom. The question is suppose the centripetal Acceleration is 6.5*10^3 times as large as the acceleration due to gravity. How many revolutions per minute is the sample making, if it is located at a radius of 5.00 cm from axis of rotation?
