If scale reads zero, then that means there must be no force on the scale. If there's no force acting on it, that's much the same as if it wasn't there to start

If scale reads zero, then that means there must be no force on the scale. If there's no force acting on it, that's much the same as if it wasn't there to start with. So, if you were to remove the scale (effectively cutting the string) the weights would stay in the same place, floating in mid air.
- dedward 16y agoI think he's assuming you are attaching the scale with the middle of the connecting-cable as the mass to be weighted and then pulling upwards on it..... which would make his description correct for that problem - but that's not the puzzle posted here.
