Three blocks A,B, and C of equal mass m are placed one over the other, one on a smooth horizontal ground as shown in figure. Coefficient of friction between any two blocks of A,B and C is 0.5 What would he the maximum value of mass of block  so that the blocks A,B and C move without slipping over each other

A thin liquid film formed between a u-shaped wire and a light slider supports a weight of (see figure). The length of the slider is 30 cm and its weight negligible. The surface tension of the liquid film is.

Surface tension is the phenomenon of a liquid's surface when it comes into contact with another phase. The least amount of surface area is typically acquired by liquids. As a result, the liquid's surface exhibits an elastic sheet-like behavior.
¶The forces of attraction between the particles of liquid and the forces of attraction of solids, liquids, or gases in contact with it affect surface tension. The energy or work requires to remove the molecules of the surface layer in a unit area is roughly equivalent to the energy responsible for the phenomenon of surface tension.

Three  masses 1 kg and 6 kg and 3 kg are connected to each other with threads and are placed on a table as shown in figure. The acceleration with which the system is moving is-ms²(g=10ms²)
