A small plastic boat loaded with pieces of steel rods is floating in a bath tub. If the cargo is dumped into the water allowing the boat to float empty, the water level in the tub will
- A. Rise
- B. Remains same
- C. Fall
- D. Cannot be estimated from the information
Answer: C. Fall
Explanation: Floating steel displaces water equal to its weight. Submerged steel displaces water equal to its volume. Since steel density > water, volume displaced is less when submerged. Total level falls.
