Physics question even tho this is a maths server, got permission from rion___

Two thin circular discs of mass m and 4m, having radii of a and 2a, respectively, are rigidly fixed by a massless, rigid rod of length l =√24a through their centers. This assembly is laid on a firm and flat surface, and set rolling without slipping on the surface so that the angular speed about the axis of the rod is a. The angular momentum of the entire assembly about the point 'O' is L→ (see the figure). Which of the following statement(s) is (are) true?
A) The center of mass of the assembly rotates about the z-axis with an angular speed of ω/5
B)The magnitude of angular momentum of the center of mass of the assembly about the point O is 81 ma²ω
C)The magnitude of angular momentum of the assembly about its center of mass is 17 ma² ω/2
D)The magnitude of the z-component of is 55 ma²ω

Hah?

[hot totem]

Are you trolling?

[deft star]

No

Why?

This is my practice question

[hot totem]

Oh

[deft star]

Yea

you could prolly refer to yt man, its a pretty difficult question to explain over text specially with my communication skills

" This assembly is laid on a firm and flat surface, and set rolling without slipping on the surface so that the angular speed about the axis of the rod is a."
are u saying the anguler velocity of rod is a which is the radius of the smaller disc?

also is it sqrt(24a) or sqrt(24) a

answer god damn it

11thie by any chance?

U should ask ur teachers ur doubts ho
