How fast must a centrifuge spin if a particle 8 cm from the axis of rotation is to experience an acceleration of 125,000 g. (g = 9.8 m/s^2)
Homework Answers
Here, we will use the concept of centripetal acceleration as the particle is moving in a circular motion
a = mv2 / r
We know that
v = rw ( no slipping condition)
so,
a = mr2w2 / r
a = mrw2
For very small particle,
a = rw2
w = sqrt (a / r)
w = sqrt ( 125000 * 9.8 / 0.08)
w = 3913.118 rad/sec
In rpm,
w = 3913.118 * (60 / 2
)
w = 37367.5
w = 37368 rpm
