A cockroach is moving with a velocity v is anticlockwise direction on the rim of a disc of radius R of mass m . The M.I. of the disc about the axis is I and its 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 ) `
