hcv sum............................... :D

draw fbd
consider Normal rxtion(of person n blck), Mg(of both), friction......

balance them
u will get d asnwer

See
Total Normal force (N) = (M + m)g
Friction = Î¼N

Force Applied by the man cannot exceed the Frictional force
Force = Friction
F = Î¼g(M+m)
This is the maximum force
