A uniform thin rod AB of mass M and length l attached to a string OA of length `(l)/(2)` is placed on a smooth horizontal plane and rotates with angular velocity omega around a vertical axis through O. A peg P is inserted in the plane in order that on stricking it the bar will come exactly to rest

A

Location of peg for rod coming to rest is `r=(5l)/(6)`

B

Location of peg for rod coming to rest is `r =(3l)/(4)`

C

Location of peg for rod coming to rest is`r=(13)/(12)l`

D

Location of peg for rod coming to rest is `r=(2l)/(3)`
