Final answer:
To find the normal force on the table by the floor, we equal it to the weight of the table, which is given as 500 N, because the table is at rest and in equilibrium.
Step-by-step explanation:
To calculate the normal force on the table, we can use the concept that the normal force (N) acting on an object at rest is equal to the weight (W) of the object. The weight is the force due to gravity and is calculated by multiplying the mass of the object by the acceleration due to gravity (g = 9.8 m/s2). In this case, however, the weight of the table is already given as 500 N. Since the table is at rest and assuming there are no other vertical forces acting on it, the normal force exerted by the floor on the table must be equal to the weight of the table to maintain equilibrium.
Therefore, the normal force on the table by the floor is 500 N.
