Q:  A force of 100N  is applied  on a block  of mass  2kg as  shown  in figure.
 The  coefficient of friction between  the surface and  the block is ¼ . Then  friction force  acting  on block  is [ g = 10 m/s2] ?

plz give me some answer. plz

Maximum friction force=1/4×100=25. But applied horizontal force is 100N which is larger than friction force.so Block will move.hence friction force is equal to mg=20N
