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.
