A rock is sinking to the bottom of the lake. The buoyant force is greater at point
 
  1) A.
  2) B.
  3) C.
  4) equal at all levels.
 
  This follows from the fact that
  5) pressure increases with depth.
  6) the same weight of water is displaced at any depth.
  7) the water is appreciably more compressed with increasing depth.
  8) position B provides a moderate answer, between the extremes.

Question 2

A boulder is thrown into a deep lake. As it sinks deeper and deeper in the water the buoyant force
 
  1) increases.
  2) decreases.
  3) remains the same.
 
  This is because the
  4) pressure increases with greater depth.
  5) pressure decreases with greater depth.
  6) volume and weight of displaced water are the same at any depth.
