A uniform cubical block of mass M is attached to a pulley. One end of a string, passing over the pulley is fixed to a light pole while is fixed on the bigger block and its another end is attached to a block of mass m as shown in figure. The maximum value of the mass m so that the block does not topple is : (string and pulley are ideal)

In the figure the pulley P moves to the right with a constant speed u . The downward speed of A is v_(A) and the speed of B to the right V_(B) .

A block of mass M is placed on a rough horizontal surface. It is connected by means of a light inextensible string passing over a smooth pulley . The other end of string passing over a smooth pulley.
