A block “a” of mass 4 kilogram is placed on another block “b” of mass 5 kilogram. And this block rest on a smooth surface. For sliding the block a on b, a horizontal force 12 n is required to be applied on it. How much maximum horizontal force can be applied on b so that both a and b move together?

Consider two blocks that are resting one on top of the other. The lower block has mass
M2 and is resting on a nearly frictionless surface. The upper block has mass M1 < M2 .
Suppose the coefficient of static friction between the blocks is µs .
a) What is the maximum force with which the upper block can be pulled
horizontally so that the two blocks move together without slipping? Draw as
many free body force diagrams as necessary. Identify all action-reaction pairs of
forces in this problem.
