In the figure shown, the minimum force F to be applied perpendicular to the incline so that the block does not slide is

Minimum horizontal force (F) required to move the block shown in diagram is__

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

A spring is attached with a block of mass m and a fixed horizontal roof as shown. The block is lying on a smooth horizontal table and initially the spring is vertical and unstretched. Natural length of spring is 3l_(0) . A constant horizontal force F is applied on the block so that block moves in the direction of force. When length of the spring becomes 5l_(0) , block leaves contact with the table. Find the constant force F, if initial and final velocity of block is zero.

A cubical box of side L rests on a rough horizontal surface with coefficient of friction p. A horizontal force F is a applied on the block as shown in Fig. 15.4.6. If the coefficient of friction is sufficiently high so that the block does not slide before toppling, the minimum force required to topple the block is

A cubical block of edge length 1 m and density 800 kg m^-3 rests on a rough horizontal surface with coefficient of friction mu . A horizontal force F is applied on the block as shown in figure. If the coefficient of friction is sufficiently large so that the block does not slide bofore toppling, then the minimum value of F to topple the block is [Take g = 10 ms^-2 ]

A block of mass 2.5 kg is kept on a rough horizontal surface. It is found that the block does not slide if a horizontal force less than 15 N is applied to it. Also it is found that it takes 5 seconds to slide through the first 10 m if a horizontal force of 15 N is applied and the block is gently pushed to start the motion. Taking g=10 m/s^2 , calculate the coefficient of static and kinetic friction between the block and the surface.

Two blocks A and B each of mass m are placed on a smooth horizontal surface. Two horizontal force F and 2F are applied on blocks A and B, respectively, as shown in fig. Block A does not slide on block B. Then then the normal reaction acting between the two blocks is (assume no friction between the blocks)
