SHM
if i put the r in the denominator as R-r ill have my answer, but that would mean that i hve written torque eqn about O. Im writing the torque eqn about IAOR but thats not working . Why?

Yea cuz the que asks u to find oscillations abt point O not iaor

Like its obvious😠it says the disc can only move along perphery of the ring withoht slipping which obv means u displace it slightly from bottom hence it will perform SHM abt O
wth man i left this que in
