A block is kept on a rough surface and applied with a horizontal force as shown which is gradually increasing for zero. The coefficient of static and kinetic friction are `1//sqrt3` then

A system of two blocks is placed on a rought horizontal surface as shown in figure below The coefficient of static and kinetic friction at two surfaces are shown A force F is horizontal applied on the upper block as shown . Let f_(1) ,f_(2) represent the frictional force between upper and lower surface of contact respectively and a_(1),a_(2) represent the acceleration of 3kg and 2kg block respectively If F is gradually increasing forcethen which of the following statement (s) contact would be true?

A block kept on a rough surface starts sliding when the inclination of the surface is theta with respect to the horizontal . The coefficient of static friction between the block and the surface is

A block is sliding on a rough horizontal surface. If the contact force on the block is sqrt2 times the frictional force, the coefficient of friction is

A block is sliding on a rough horizontal surface. If the contact force on the block is sqrt2 times the frictional force, the coefficient of friction is

A block is in limiting equilibrium on a rough horizontal surface. If the net contact force is sqrt3 times normal force, the coefficient of static friction is

A wooden block of mass M resting on a rough horizontal surface is pulled with a force F at an angle  with the horizontal. If  is the coefficient of kinetic friction between the block and the surface, then acceleration of the block is -
