Question

A typical laboratory centrifuge rotates at 3700 rpm . Test tubes have to be placed into a centrifuge very carefully because of the very large accelerations. Part A What is the acceleration at the end of a test tube that is 10 cm from the axis of rotation

    Answer:

    Explanation:

    acceleration of test tube

    = ω² R

    = (2πn)² R

    = 4π²n²R

    n = no of rotation per second

    = 3700 / 60

    = 61.67

    R = .10 m

    acceleration

    = 4π²n²R

    = 4 x 3.14² x 61.67² x .10

    = 14999 N Approx
