Question

When you push on a box with a 200-N force instead of a 50-N force, you can feel that you are making a greater effort. When a table exerts a 200-N normal force instead of one of smaller magnitude, is the table really doing anything differently?

a) Yes
b) No

Answer 1

When a table exerts a 200-N normal force instead of a smaller magnitude, it is not doing anything differently. The normal force is a force exerted by a surface to support the weight of an object placed on it. It is always equal in magnitude and opposite in direction to the weight of the object.

Step-by-step explanation:

When a table exerts a 200-N normal force instead of a smaller magnitude, it is not doing anything differently. The normal force is a force exerted by a surface to support the weight of an object placed on it. It is always equal in magnitude and opposite in direction to the weight of the object. So, regardless of the magnitude of the normal force, the table is simply supporting the weight of the object placed on it.
