Density and Pressure

Density and Pressure problem 53

A closed 3.0 litre bottle with a weight of 2.0 kg is completely immersed in water.

  • How many litres of water has the bottle displaced?

  • What is the mass of the displaced water?

  • What is the upthrust on the bottle?

  • What force F of the arm do we have to apply to the bottle to keep it under the water?

  • If the bottle is lowered and released so that it rises freely towards the water level, what is the resultant of all the forces on the bottle when it is released?

  • In which direction does the resultant of the forces point as the bottle moves toward the water surface?
