Question

The figure shows two circular discs 'A' and

'B' with masses '3m' and 'm' and radii 'R' and

'3R' are hinged at their center respectively, if

a particle of 'm' is attached to disc 'B' at a

distance '2R' from its center and the system is

released from rest. Then the torque on disc

'A' will be (Assuming there is no slipping

between the discs).
