A body of mass 2 kg is kept by pressing to a vertical wall by a force of 100 N . The coefficient of friction between wall and body is 0.3. Then the frictional force is equal to

A block of weight 5N is pushed against a vertical wall by a force 12 N. The coefficient of friction between the wall and block is 0.6. The magnitude of the force exerted by the wall on the block is

A block of weight 5 N is pushed against a vertical wall by a force 12 N . The coefficient of friction between the wall and block is 0.6 . Find the magnitude of the force exerted by the wall on the block :

A block of weight 5 N is pushed against a vertical wall by a force 12 N . The coefficient of friction between the wall and block is 0.6 . Find the magnitude of the force exerted by the wall on the block :

A block of mass 2kg is held at rest against a rough vertical wall by passing a horizontal (normal) force of 45 N . Coefficient of friction between wall and the block is equal to 0.5. Now a horizontal force of 15 N (tangential to wall) is also applied on the block. Then the block will :

A block of weight 5N is pushed against a vertical wall by a force 12 N. The coefficient of friction between the wall and the block is 0.6. The- magnitude of the force exerted by the wall on the block is

A body of mass 0.2 kg is pressed into a vertical wall normally with a horizontal force 20 N. Coefficient of friction is 0.9. Another horizontal force of 2N is applied on the body in the vertical plane. The frictional force acting on the body is K sqrt2N. The value of K is
