A horizontal force of 20 N is applied on the block of mass 4 kg on the rough horizontal table. If the block does not slip of the table, how much frictional force the table is applying on the block? What can be said about the coefficient of static friction between the block and the table? (g= 10m/s2 )

dear kaushik

                     since the body is at rest so static friction force is acting on the body , the property of static friction is that it is self adjustable force that means if we apply a force which is less than maximum static friction force then force of friction is equal to applied force ...

friction force = 20N

and nature is static
