NEET2015Physics-Compressibility
NEET 2015 Physics Fluid Mechanics MCQ Question
Type: MCQ-numerical-Medium-Class 11
The approximate depth of an ocean is 2700 m. The compressibility of water is 45.4 × 10⁻¹¹ Pa⁻¹ and density of water is 10³ kg/m³. What fractional compression of water will be obtained at the bottom of the ocean?
A
0.8 × 10⁻²
B
1.0 × 10⁻²
C
1.2 × 10⁻²
D
1.4 × 10⁻²
Correct Answer
Option B
Detailed Explanation
The fractional compression is given by the product of compressibility and pressure. The pressure at the bottom is ρgh, leading to a fractional compression of 1.0 × 10⁻².
