A cubical block of density ρ is floating on the surface of water. Out of its height L, what fraction x is submerged in water? The vessel is in an elevator accelerating upward with acceleration a. Which of the following statements is true regarding the fraction of the block submerged?

Options

  1. AThe fraction of the block submerged increases with the acceleration of the elevator.
  2. BThe fraction of the block submerged decreases with the acceleration of the elevator.
  3. CThe fraction of the block submerged remains constant regardless of the acceleration of the elevator.
  4. DThe fraction of the block submerged is zero in an accelerating elevator.

Correct answer

C. The fraction of the block submerged remains constant regardless of the acceleration of the elevator.

Step-by-step solution

Correct Option is : (C) The fraction of the block submerged remains constant regardless of the acceleration of the elevator.
