A raw egg and a hard boiled egg are made...

A raw egg and a hard boiled egg are made to spin on a table with the same angular speed about the same axis. The ration of the time taken by the two to stop is

A

`= 1`

B

`lt 1`

C

`gt 1`

D

none of the above

Text Solution

Verified by Experts

The correct Answer is:
B
A raw egg has some fluid in it and a hard boiled egg is solid from inside. On spinning, the fluid is thrown outwards. Therefore, `I_(r) gt I_(b)`
As `I xx omega = constant :. omega_(r) lt omega_(b)`
or `(omega_(r))/(omega_(b)) lt 1 :. (t_(r))/(t_(b)) lt 1`
