shm- rod in a rolling ring
could someone pls share the soln? I tried using the method of assuming it to be like a compound pendulum. the torque due to mg in that case, idk im getting it wrong.

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.is the cylinder attached with the tube?
yeah prolly, since the q says the rod has been soldered
btw i just realised i gave the wrong title
basically first find center of mass along radius at any angle theta, which is just R/2 from center then use torque equation and also since its rolling so friction will be mRalpha and yes solve it
yeah i was gettin this too.. but i used the compound pendulum method, assuming the ground point to be like a hinge
the given ans is A in the book. with a 4 instead of 2
it's wrong ig then
i'll look at this again tmrw.. tysm
and like in the soln instead of using 2mgd they've written mgd (d = com to hinge distance = r/2)
oh i think thats incorrect total mass is 2m i checked online too it seems B
yeah.. okay, then it's some anskey error then
Thanks a lot @integralofe^2v
