The block of mass 4kg is placed on a rough horizontal surface having the coefficient of kinetic and static friction as 0.4 and 0.5 respectively. If a force of 4N is applied to the body, then the frictional force acting on the body will be [g= m/s^2 ]

A block of mass 2kg is resting on a rough horizontal surface.The coefficients of static and kinetic frictions between the block and surface are 0.7 and 0.6 respectively.A horizontal force F=(4N/s)times t is applied on the block at t=0.At t=4s ,the force of friction on the block is (take g=10m/s^(2) )
