A rectangular block of wood floats in water with two-thirds of its volume immersed. When placed in another liquid, it floats with half of its volume immersed. Calculate the relative density of the liquid
- A. 1.43
- B. 1.33
- C. 1.00
- D. 0.75
Correct Answer: D. 0.75
Explanation
R.D = \(\frac{\text{volume of liquid displaced}}{\text{volume of water displaced}}\)
= \(\frac{1}{2} - \frac{2}{3} = \frac{1}{2} \times \frac{3}{2} = \frac{3}{4}\)
= 0.75
