f1+f2 =10N f1=friction b/w floor and B f2 = friction b/w B and A m1=8Kg; m2=2kg (mew)1=0.5 (mew)2=0.4 f1=R(mew)1 f1=(m1+m2)g(mew)1 f1=(2+8)×10×0.5 f1=50N f1+f2=10N f2=-40N -ve due to opposition

1st equation will be f1+f2=10Nf1 force of friction between a and b blockf2 force of friction between b and surfacef1=8Nf2=50NTherefore the force applied 10N is less than the frictional force of 50N. So the block will not move and the friction is limiting friction. And before limiting there is static friction which is a self adjusting force.Static friction is -f1
