• Multi-correctmediumFluid Mechanicspascal law and buoyant force

  A vessel containing water is placed on a weighing machine. Which statements are correct?

  Select all that apply

  • Option A

    If a body is immersed while suspended from an external support without touching the vessel, the scale reading increases by an amount corresponding to the buoyant force.

  • Option B

    The spring-balance reading of an immersed body decreases by the buoyant force.

  • Option C

    If a body is tied to the bottom and the entire body-liquid-vessel system is on the weighing machine, the final scale reading includes the full weight of the body.

  • Option D

    The buoyant force on an immersed body and the downward force exerted by that body on the liquid form an action-reaction pair.
