Block A mass 2 kg is placed over a block
B mass 8 kg. The
combination is placed on a rough horizontal surface. If
g=10ms−2,
coefficient offiiction between
B and floor
=0.5, coefficient offfiction
betweenA and
B=0.4 and a horizontal force on 10
N is placed of8 kg
block, then the force friction between A and
B is:
