Hollow or Solid


Petr has 2 rigid bodies 'A' and 'B': one is a hollow cylinder, the other solid. He allows them to roll (from rest) from the top of a circular track.

'A' displaces by an angle 'Qa' before losing contact with the track. 'B' displaces by 'Qb'. Also Qa>Qb.

Which is which?

    hi @khilesh:

    try not to explain the solution in the first 6-7 comments. doing so gives the other readers a 'hint' or a 'mental set'.

    A:Hollow cylinder
    B:Solid cylinder
    (Assuming same mass and radii of both cylinders)?
