The density of gold is 19 times that of water. If you take a gold crown weighing 24 N and submerge it in water, how much upward force must you exert on the submerged crown to keep it from accelerating?

• physics -

19 x water weight for same volume MINUS water weight for same volume.

The result is 18 times the weight of the same volume of water, or 18/19 of the weight of the crown.
