How fast in rpm must a centrifuge rotate if a particle 7.0cm from the axis of rotation is to experience an acceleration of 200000 g's?
Homework Answers
centrifuge acceleration = r
2
in rad/s
here acceleration =200000g m/s2 (g=9.8
m/s2 )
2 * 105 * 9.8 = 0.7 * 10-2 *2
2 =
280000000
= 16733.2
rad/s
=159790.29
