Answer: 235.2 N
Step-by-step explanation:
The Normal force is the force provided when two objects are in contact that will prevent them from going through each other. It is called the Normal force because normal means perpendicular and the normal force is always perpendicular outward from the surface touching. The box is in contact with the floor which holds it up and provides the normal force. Since the block isnt accelerating up or down the normal force on the box must be equal to the weight of the block.
Weight= Force of gravity = m (g) = 24 *9.8= 235.2 N = Normal force
