AP Physics 1· difficulty 2/5

A solid object suspended just below the water's surface and one at the bottom of the tank experience

  • A

    Same buoyant force

  • B

    Buoyancy decreases with depth

  • C

    Zero buoyancy at the bottom

  • D

    Buoyancy increases with depth

Explanation

Buoyancy depends on <strong>displaced volume</strong> (and fluid density), not depth. As long as the object is fully submerged, FBF_B is constant.
