Question

Assertion (A) If a piece of ice floats on a water surface, then its $\left(\frac{1}{10}\right)$ th part of the total volume remains above the surface and $\left(\frac{9}{10}\right)$ th part remains submerged.

Reason (R) This is because the ratio of the density of ice to the density of water is equal to the ratio of total volume of ice inside water to the total volume of ice.

• A. Both A and R are individually true, but R is the correct explanation of A
• B. Both A and R are individually true and R is not the correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

The correct option is A Both A and R are individually true, but R is the correct explanation of A

The Assertion is correct, 90% of ice by volume is submerged.

The submerged part depends on the specific gravity of the ice with respect to water. So the reason explains the Assertion.

So option A is correct.
