A cord is wrapped on a pulley (disk) of mass M and radius R as shown in figure. To one end of the cord, a block of mass M is connected as shown and to other end in (a) a force of 2Mg and in (b) a block of mass 2M. Let angular acceleration of the disk in A and B is α A and α B , respectively, then :(cord is not slipping on the pulley)

A rectangular block of mass M and height a is resting on a smooth level surface. A force F is applied to one corner as shown in Fig. At what point should a parallel force 3F be applied in order that the block shall undergo pure translational motion? Assume normal contact force a between the block and surface passes through the centre of gravity of the block.
