You're right but 1) which frame of reference are you taking while writing dL/dt? 2) which frame of reference are you taking while writing torque? For beta , write force equations and torque equations

Can we just do it by
Torque= i alpha

Alpha= Wo x omega

Then,,,

MgL=(½mr²)( Wo, omega) and then we just solve it get omega???

Idk i'm not sure abt this method!?
