Question

Consider the video tutorial you just watched. Suppose that we repeat the experiment, but this time we replace the original 56- magnet with a more powerful magnet of the same mass. As you know from experience, the more powerful a magnet is, the more strongly it attracts or repels other magnets or magnetic objects. You have also probably noticed that magnetic forces fall off sharply with distancetwo magnets that interact strongly across a distance of millimeters interact more weakly at a distance of a centimeter. (In fact, the strength of the force falls off with the square of the distance.) With the magnet hovering above the base, what will the scale read? The scale has been zeroed (tared) to subtract the weight of the base.

Explanation / Answer

It will weigh 56. The base is still exerting the same amount of force to hold it up
