This tag is for the classical concept of forces, i.e. the quantities causing an acceleration of a body. It expands to the strong/electroweak force only insofar as they act comparable to ‘classical’ forces. Use the [particle-physics] tag for decay channels due to forces and [newtonian-mechanics] or one of the other subtopics of [classical-mechanics] for the dynamics of classical systems.

Why is the normal force $(M+m)g$?
First thing is friction occurss in pair , so when small box is stationary in vertical direction that means it's weight mg is balanced by the force of friction on it in upward direction that's is u_2* …
