A wooden block of mass 100 kg rests on a flat wooden floor, the coefficient of friction between the two being `0.4`. The block by a rope making an angle of `30^(@)` with the horizontal. What is the minimum tension along the rope that just makes the rope sliding?

A block of mass 50 kg can slide on a rough horizontal surface. The coefficient of friction between the block and the surface is 0.6. The least force of pull acting at an angle of 30^(@) to the upwawrd drawn ve3rtical which causes the block to just slide is

A block of mass 1kg is at rest on a horizontal table. The coeficient of static friction between the block and the table is 0.5 . The magnitude of the force acting upward at an angle of 60^(@) from the horizontal that will just start the block moving is.

A wooden block of mass m resting on a rough horizontal table (coefficient of friction = mu ) is pulled by a force F as shown in figure.The acceleration of the block moving horizontally is :

A block of mass m rests on a rough inclined plane. The coefficient of friction between the surface and the block is µ. At what angle of inclination theta of the plane to the horizontal will the block just start to slide down the plane?

A block A of mass 2 kg rests on another block B of mass 8 kg which rests on a horizontal floor. The coefficient of friction between A and B is 0.2 while that between B and floor is 0.5 .When a horizontal floor F of 25 N is applied on the block B the force of friction between A and B is

A block A of mass 2 kg rests on another block B of mass 8 kg which rests on a horizontal floor. The coefficient of friction between A and B is 0.2 while that between B and floor is 0.5. when a horizontal force of 25 N is applied on the block B. the force of friction between A and B is

In the figure shown, the coefficient of static friction between the block A of mass 20 kg and horizontal table is 0.2. What should be the minimum mass of hanging block just beyond which blocks start moving?

A rope of mass 0.2 kg is connected at the same height of two opposite walls. It is allowed to hang under its own weight. At the contact point between the rope and the wall, the rope makes an angle theta=30%^(@) with respect to horizontal. The tension in the rope at its midpoint between the walls is
