SUMMARY
The discussion centers on the dynamics of a block of mass 'm' resting on the hypotenuse of a right triangular wedge of mass 'M'. The normal force acting on the block is defined as N=mg cos(α), where α is the lower angle of the wedge. The horizontal force exerted between the block and the wedge is calculated as F=N sin(α)=mg cos(α) sin(α). Consequently, the acceleration of the wedge is derived as a=F/M=m g cos(α) sin(α)/M. The query regarding the condition under which 'm' remains stationary is clarified to involve its position relative to the wedge.
