A centrifuge spins a solution of particles in order to separate particles of different masses. A certain particle must spin at 34,000 rpm at a radius of 6.9 cm from the center of rotation before it will adequately separate in the solution. a) What is the linear speed of the particle as it rotates? b) How many g's of acceleration are required for particle separation? (Hint, this value may seem enormous, but must be to separate particles)
