The angular frecuancy needed for a centrifugal to produce an acceleration of 1000 g at a radius arm of 10 cm ,is

A

`1.99xx10^(3) rev//min`

B

`3.99xx10^(3) rev//min`

C

`4.99xx10^(3) rev//min`

D

`2.99xx10^(3) rev//min`

Text Solution

Verified by Experts

The correct Answer is:
D

`a=r omega^(2)`
` thereforen=sqrt((a)/(r 4 n^(2))`
`sqrt((1000)/(0.1xx4xx10))=50 rps=3xx10^(3) rpm`.
