Four identical uniform rods of mass M=6k...


Four identical uniform rods of mass `M=6kg` each are welded at their ends to form a square and then welded to a uniform ring having mass m=4kg & radius R=1m the system is allowed to roll down on the rough and fixed incline of inclination `theta=30^(@)` (assume no sliding anywhere)
Q. The moment of inertia of system about the axis of ring will be-

A

`20 kg m^(2)`

B

`40 kg m^(2)`

C

`10 kg m^(2)`

D

`60 kg m^(2)`
