sir how can you conserve angular momentum about about AOR of cylinder??since weight of small m is acting is acting vertically downward.

There is two reason behind this
1. Passing of line of impact of mg from the point about which we conserve momentum
2. Second one is cancelling out by producing same torque by normal
I guess the first reason is most suitable for your doubt.

hey
1)it's not passing through the point which we conserve momentum
2)if you are correct -normal reaction and weight are at same distance implies that they are equal..if they are equal then it should stay there itself i.e.it should not move but sir considered it is moving..thanks for repley

In case of collisions compared to impulsive forces (short duration & high magnitude) all other finite forces can be neglected...
