Specific gravity of a metal, which weighs 5 kg in air and 4 kg when submerged in water, will be_____________________?
Correct answer: A. 5
- A. 5
- B. 1.25
- C. 2.5
- D. 3.75
Explanation
The loss of weight in water is 5 - 4 = 1 kg, which equals the buoyant force and the weight of displaced water. Therefore, specific gravity = weight in air divided by loss of weight = 5/1 = 5.
