A cubical block is floating in a liquid with one third of it's volume immersed in the liquid. When the whole system accelerates upwards with acceleration of g / 2 .

Options

  1. AThe fraction of volume immersed in the liquid will change.
  2. BThe buoyancy force on the block will change.
  3. CThe buoyancy force will increase by 50 percent.
  4. DThe pressure in the liquid will increased.

Correct answer

D. The pressure in the liquid will increased.

Step-by-step solution

If the volume immersed initially is (V / 3) . Then V 3 g=m g ....(i) If the volume immersed when the system accelerates is V ^ then V^ (g+ g 2 )-m g= m g 2 V^ = V 3
