The critical angular velocity w of a cylinder inside another cylinder

1.	The critical angular velocity w of a cylinder inside another cylinder containing a liquid at which its turbulence occurs depends on viscosity eta, density d and the distance x between the walls of the cylinders. Then w is proportional to
Answer» `(ETA )/( X^(2) d)` `(eta)/( d^(2) x)` `( eta^(2) )/( XD)` `( xd)/( eta)` ANSWER :A
