Question

8) A ring of mass M and radius R is rolling without slipping with
angular velocity ω on the horizontal plane as shown the figure
The magnitude al angular momentum of ring about the point of the
contact of the ring (Answer 2)
( 1 )   M R 2   ω ( 2 )   2 M R 2   ω
( 3 )   1 2 M R 2   ω ( 4 )   Z e r o

Dear Student ,
Here in this case from the given data we can write that the angular
momentum of the ring about the point of contact is = Angular
momentum of the body due to translation and rotation + angular
momentum of the body about the centre of mass
= 32MR2ω+12MR2ω=2MR2ω
so here the option 2 is the correct option
Regards
