An object is floating in a liquid, kept in a container. The container is placed in a lift. Choose the correct option(s)

Options

  1. ABuoyant force increases as lift accelerates up
  2. BBuoyant force decreases as lift accelerates up
  3. CBuoyant force remains constant as lift accelerates
  4. DThe fraction of solid submerged into liquid does not change

Correct answer

D. The fraction of solid submerged into liquid does not change

Step-by-step solution

Buoyant force F _ B = V _ e g _ eff If lift accelerates g_ eff =g+a
