The figure(Figure 1) shows two strong magnets on opposite sides of a small table

Question

The figure(Figure 1) shows two strong magnets on opposite sides of a small table. The long-range attractive force between the magnets keeps the lower magnet in place.

Part D

Suppose the weight of the table is 29 N , the weight of each magnet is 2.8 N , and the magnetic force on the lower magnet is three times its weight. Find the magnitude of each of the forces shown on your free-body diagram for the upper magnet.

Express your answers using two significant figures. Enter your answers numerically separated by commas.

Part E

Find the magnitude of each of the forces shown on your free-body diagram for the table.

Express your answers using two significant figures. Enter your answers numerically separated by commas.

Part F

Find the magnitude of each of the forces shown on your free-body diagram for the lower magnet.

Problem 7.19 The figure(Figure 1) shows two strong magnets on opposite sides of a small table. The long-range attractive force between the magnets keeps the lower magnet in place Figure 1 | of 1 Upper magnet Lower magnet

Explanation / Answer

The weight of the table has nothing to do with the problem. The force of the lower magnet on the upper magnet and vice versa will be equal in magnitude and opposite in direction by Newton's Third Law. The magnitude of the force on the lower magnet is 2.8 * 3 N, or 8.4 N.

The direction of the magnetic force on the lower magnet is upward, toward the upper magnet. Conversely, the magnetic force of the lower magnet on the upper magnet will be downward, also with a magnitude of 8.4 N.
