Pressure in a fluid rises with depth, which is why a container's bottom supports:
AHalf the fluid weight
BNone of the weight
CThe weight of the fluid
DThe weight of the air
Answer & Solution
Correct answer: C. The weight of the fluid
1. Depth and pressure are directly linked in a static fluid.
2. The forces on a submerged body are larger underneath, due to greater depth.
3. A container's bottom supports the weight of the fluid in it.
4. That accumulated weight is what raises the pressure at depth.
5. The same depth dependence produces the buoyant force on a submerged object.
