Question

The coefficient of static friction between the
two blocks shown in figure is u and the table is
smooth. What maximum horizontal force F can
be applied to the block of mass M so that the
blocks move together ?​

Answer 1

Answer:

Explanation:

acceleration of system = F/m1+m2

frictional force acting on blocks =

F-f=MF/m1+M

f=m1F/M+m1

it should be less than static frictional force

m1F/M+m1 <= um1g

F<= ug(M+m1)
