what is the force work on object B in terms of a ?

i know that the frictinon should be bigger than the force mBg for that the object will not fall down.
but how to express it in terms of a ??

TNX .

If you are looking for the forces acting on B, you must draw a Free Body Diagram of that object, and identify all the forces acting on it, including its weight, the friction force, and the normal force between the 2 blocks. Use Newton's laws in the x and y direction to solve for the minimum acceleration required.

It can't be bigger; for static equilibrium in the y direction, it must be the same.
