A wooden box is sitting on a table. The normal force on the box from the table is 75 N. A second identical box is placed on top of the first box. The normal forces on the first box by the table will ______?
Explanation
Since the two boxes are identical, the weight of the second box is equal to the weight of the first box.
The normal force from the table will increase to support the combined weight of both boxes, which is 150 N (2 x 75 N).
