To solve the problem step by step, we will analyze the forces acting on the block and determine the force exerted by the block on the horizontal surface. ### Step 1: Identify the forces acting on the block The block has a weight of 4.0 N acting downward due to gravity. An upward force of 1.0 N is applied through a vertical string. ### Step 2: Calculate the net force acting on the block The net force acting on the block can be calculated by considering the downward force (weight of the block) and the upward force (force from the string). ...
