How fast (in rpm) must a centrifuge rotate if a particle 6.0 cm from the axis of rotation is to experience an acceleration of 70000 g’s?

centripetal acceleration is
a=w^2 r
where w is the angular velocity in rad/s and r is the distance from the rotation axis
if we want a=70,000 g = 686,000m/s/s
we have
w = sqrt[a/r] = sqrt[686000/0.06] = 3381.3 rad/s
3381.3 rad/s = 538.4rev/s = 32,305.6rev/min
97836 rpm
190555555.55 r/s or 1820594479.83 rpm can u do that?????
