Find the required angular speed, ω, of an ultracentrifuge for the radial acceleration of a point 2.00cm from the axis to equal 6.00×105 g (where g is the acceleration due to gravity).

Answer 1

r w^2 = Ac = 6*10^5*9.81

w^2 = 58.9 * 10^5 /.02 = 29.4 *10^7
= 2.94 * 10^8

w = 1.72 * 10^4

= 17,200 radians/sec
