Question

A boat with heavy cargo is in a swimming pool. Cargo is thrown into pool. Water level:
  1. A
    Rises
  2. B
    Falls
    Correct
  3. C
    Stays same
  4. D
    Depends on cargo density

Correct answer

Falls

Explanation

Floating boat displaces water equal to its total weight (boat + cargo). Cargo in water (if denser than water) displaces only its own volume. If cargo density > water density, total displaced volume decreases → level falls.
