Two blocks are held against the wall by applying a horizontal force as shown in the diagram. The wall is frictionless but the surface between the blocks is rough.

Can these blocks remain in the equilibrium

Can these blocks remain in the equilibrium, answer with explanation?

no, both blocks will fall, as the wall is frictionless. even if there exists a frictional force at the interfaces of the blocks that will cancel out each other as internal force for both the blocks as an integrated system. Result is: both the blocks will fall.

The 2 blocks together will be falling at an acceleration of g but there wont be any relative motion between the 2 blocks as long as the horizontal forces keep following the blocks.

Wall is frictionless
There is friction between the blocks
