Two strong magnets on opposite sides of a small table are shown. The long-range attractive force between the magnets keeps the lower magnet in place. Suppose the weight of the table is 19.7 N, the weight of each magnet is 4.17 N, and the magnetic force on the lower magnet is 5.39 times its weight. Find the magnitude of the force of the lower magnet on the upper magnet.

    The attractive force is 5.39N as given in the problem. The lower magnet pulls on the upper with that force, come hell or high water.

    thank you
    do you know how i would figure out the normal forces of the table to each of the magnets?

    A basketball player runs down the court, following the path indicated by the vectors A, B, and C in Figure 3-35. The magnitudes of these three vectors are: A = 12.0 m, B = 20.0 m, and C = 7.0 m. Let the +x axis point to the right and the +y axis point to the far side of the court.
