Question

Rank the boxes on the basis of the magnitude of the normal force acting on them. Rank from largest to smallest. To rank items as equivalent, overlap them.

Answer 1

The normal force on box A (on level ground) is equal to the weight of the box, while the normal force on box B (on an inclined plane) is less than the weight of the box.

Step-by-step explanation:

The normal force is the force exerted by a surface to support the weight of an object resting on it.

When comparing the normal forces on the two boxes A and B, we need to consider the forces acting on each box.

1. For box A on level ground, the normal force is equal in magnitude and opposite in direction to the weight of the box. Therefore, the normal force on box A is equal to the weight of the box.
2. For box B on the inclined plane, the normal force is less than the weight of the box. This is because the weight has two components - one acting vertically downward and one parallel to the inclined plane. The normal force only balances the vertical component of the weight.

Therefore, the ranking of the normal forces from largest to smallest is: Box A (on level ground), Box B (on the inclined plane).
