How fast (in rpm) must a centrifuge rotate if a particle 6.00 cm from the axis of rotation is to experience an acceleration of 1
astra-53 [7]
The acceleration experienced by the particle is given by
a=113000 g=113000 \cdot 9.81 m/s^2
This corresponds to the centripetal acceleration of the motion, which is related to the angular speed \omega of the particle and its distance r from the axis by the relationship
a= \omega ^2 r
In our problem, r=6 cm=0.06 m, so we can solve for \omega:
\omega = \sqrt{ \frac{a}{r} } = \sqrt{ \frac{113000 \cdot 9.81 m/s^2}{0.06 m} }=4298 rad/s
However, we must convert it into rpm (revolution per minute).
We know that 1 rad corresponds to ( \frac{1}{2 \pi} ) revolutions, while 1 s =  \frac{1}{60} min. So we the conversion is\omega = 4298 rad/s \cdot ( \frac{1}{2\pi} rev/rad )( 60 s/min)=41067 rpm
