A cockroach is moving with velocity v in...

A cockroach is moving with velocity `v` in anticlockwise direction on the rim of a disc of radius `R` of mass `m`. The moment of inertia of the disc about the axis is `I` and it is rotating in clockwise direction with an angular velocity `omega`. If the cockroach stops, the angular velocity of the disc will be

A

`(l omega)/((1+mr^(2)))`

B

`( l omega + mvr)/( l + mr^(2))`

C

`( l omega - mvr)/( l + mr^(2))`

D

`( lomega+ mvr)/( l ) `
