There are two identical square metallic plates kept on a rough horizontal floor at `t=0`, plates are given angular velocity `omega` and it is given that plate `1` is rotating about its centre `A` and plate `2` is rotating about one of its centre `O`. If `t_(1)` and `t_(2)` are the time taken by both the plates to come to rest then `(t_(1))/(t_(2))` is (Both are independent cases)

A

`(1)/(2)`

B

`2`

C

`(1)/(4)`

D

`4`

Text Solution

Verified by Experts

`tau alpha mgd`
`I.((dw)/(dt)) alpha mgd`
and `I=K.md^(2)`
Therefore `(dw)/(dt) alpha (1)/(d)`(Angular Acceleration of plate is independent of mass)
