SUMMARY
The magnitude of the force exerted by a block on a horizontal surface is determined by its weight and any applied forces. In this case, a block weighing 3.0 N is at rest, and an upward force of 0.9 N is applied via a vertical string. The force on the horizontal surface is calculated as the weight of the block minus the upward force, resulting in a net force of 2.1 N acting downward on the surface.
