Figure shows a string stretched by a block going over a pulley. The string vibrates in its tenth harmonic in unison with a particular tuning fork. When a beaker containing water is brought under the block so that the block is completely dipped into the beaker, the string vibrates in its eleventh harmonic. Find the density of the material of the block.

Two identical blocks are attached by a massless string running over a pulley as shown in figure. The rope initially runs over the pulley at its (the rope's) midpoint, and the surface that block 1 rests on is frictionless. Blocks 1 and 2 are initially at rest when block 2 is released with the string taut and horizontal. Assume that the initial distance from block 1 to the pulley is the same as the initial distance from block 2 to the wall.

A block of mass M= 4 kg of height and breath b is placed on a rough plank of same mass M . A light inextensible string is connected to the upper end of the block and passed through a light smooth pulley as shown in figure. A mass m =1 kg is hung to the other end of the string. a. What should be the minimum value of coefficient of friction between the block and the plank so that, there is no slipping between the block and the wedge? b. Find the minimum value of b//h so that the block does not topple over the plank, friction is absent between the plank and the ground.
