Force `F` is graduallly increased from zero .Determine whether the block will first slide or lift up?

A block of mass m placed on an incline just begins to slide when inclination of the incline is made theta_(0) = 45^(@) . With inclination equal to theta = 30^(@) , the block is placed on the incline. A horizontal force (F) parallel to the surface of the incline is applied to the block. The force F is gradually increased from zero. At what angle a to the force F will the block first begin to slide?

A block is being pulled by a force F on a long frictionless level floor. Magnitude of the force is gradually increases from zero until the block lifts off the floor. Immediately before the block leaves the floor, its acceleration is

A block A (5kg) rests over another block B (3kg) placed over a smooth horizontal surface. There is friction between A and B. A horizontal force F_1 gradually increasing from zero to a maximum is supplied to A so that the blocks move together without relative motion. Instead of this another horizontal force F_2 , gradually increasing from zero to a maximum is supplied to B so that the blocks move together without relative motion. Then

A block A (5kg) rests over another block B (3kg) placed over a smooth horizontal surface. There is friction between A and B. A horizontal force F_1 gradually increasing from zero to a maximum is spplied to A so that the blocks move together without relative motion. Instead of this wanother horizontal force F_2 , gradually increasing from zero to a maximum is spplied to B so that the blocks move together without relative motion. Then

In the figure shown, horizontal force F_(1) is applied on a block but the block does not slide. Then as the magnitude of vertical force F_(2) is increased from zero the block begins to slide, the correct statement is
