How does the force on the scale change when the mass is completely submerged
(but not touching the bottom) compared to before the mass entered the water?
The force increases by an amount equal to the weight of the water displaced by
the weight's volume.
The force decreases, because the water above the weight is partially resting on
the weight and is held up by the string, reducing the overall mass on the scale.
The force is unchanged (the mass is suspended by the string!)
The force increases by an amount equal to the full weight of the mass, mg
