For the arrangement shown in fig., the tension in the string to prevent it from sliding down, is - (mu=sqrt(3))

A smooth washer impinges at a velocity 'v' on a group of three smooth identical blocksresting on a smooth horizontal surface as shown in fig. Mass of each block is equal to mass of the washer. The diameter of the washer and its height are equal to edge of the block. The velocity of blocks (2) and (3) after collision is

Three identical smooth cylinders, each of mass m and radius r are resting in equilibrium within a fixed smooth cylinder of radius R (only a part of this cylinder has been shown in the fig). Find the largest value of R in terms of r for the small cylinders to remain in equilibrium.

Four block are arranged on a smooth horizontal surface as shown in figure .The masses of the blocks are given (see the fig ) The coefficient of static friction between the top and the bottom blocks is mu_(s) What is the maximum value of the horizontal force F applied to one of the bottom blocks as shown that makes all four block with the same acceleration ?
