A uniform disc of mass `m` and radius `R` rotates about a fixed vertical axis passing through its centre with angular velocity `omega`. A particle of same angular velocity mass m and moving horizontally with velocity `2omegaR` towards centre of the disc collides and sticks to its rim.  The impulse on the particle due to the disc is
