1. The problem statement, all variables and given/known data A chemistry lab centrifuge spins creating a circular trajectory for the solutes in the test tubes with a diameter of 20cm. If an acceleration of 10 times the Earth's gravitational acceleration is required, which of the following is a minimum frequency that must be achieved by the centrifuge? Hint: Circumference = 2∏r 2. Relevant equations 3. The attempt at a solution Ok, I tried using A=V^2/r then used V=2∏fr to solve for frequency but the answer I'm getting is not listed in the multiple choices. Am I missing a step or am I completely off track on how to solve this problem?
