D block remaining parts

A homogeneous block rests against a vertical wall for which the coefficient of friction is 1//2 . A force 'F' is applied to the block in the direction as shown in figure. Find the maximum magnitude of applied force 'F' such that block remains in rest.

A massless spring of stiffness 400 N/m is fastened at left end to a vertical wall as shown in the figure I. initially block C of mass 2 kg and block D of mass 5 kg rest on horizontal surface with block C in contact with spring (But not compressiong it.) and the block D in contact with block C block C is moved leftward compressing spring by a distance of 0.5 m and held in place while block D remains at rest as shown in the figure. Now block C is released and it accelerates to the right towards block D the surface is rough and the coefficient of friction between each block and surface is 0.1 The block collide Instantaneously stick together and move right find the velocity of combined system just after collision.

A block of mass 10 kg is placed on rough inclined plane of inclination angle 37^(@) .Coefficient of friction between block & plane is 0*8 , find minimum magnitude of F so that block remains at rest .

If you sling a thin wire loop around a block of ice and attach to it a weight of several kilograms then after some time the wire will pass through the block of ice, but the block remains intact (Fig. 23.2). Explain this phenomenon.

From a uniform square plate, one-fourth part is removed as shown. The centre of mass of remaining part will lie on

The minimum value of mass m for which the 100 kg block can remain in static equilibrium is

A cylindrical block of the density rho is partically immersed in a liwuid of density 3rho . The plane surface of the block remains parallel to the surface of the liquid. The height of the block is 60 m . The block perform SHM when displaced form its mean position [Use g = 9.8 m//s^(2) ]

Two forces are applied on a system of blocks as shown. The block remains in equilibrium on the smooth surface. Then choose the correct option(s).

There is some liquid in a closed bottle. The amount of liquid remains constant as time passes. The vapor in the remaining part.
