Paragraph: A wooden cylinder of diameter 4 r , height H and density / 3 is kept on a hole of diameter 2 r of a tank, filled with liquid of density as shown in the figure. Question: The block in the above question is maintained at the position by external means and the level of liquid is lowered. The height h₂ when this external force reduces to zero is

Options

  1. A4 h 9
  2. B5 h 9
  3. Cremains same
  4. D2 h 3

Correct answer

A. 4 h 9

Step-by-step solution

Again equating the forces, we get h₂= 4 h 9
