NEET 2026 Physics Pressure in Fluids MCQ Question
Type: MCQ-numerical-Medium-Class 11
A submarine is designed to withstand an absolute pressure of 100 atm. How deep can it go below the water surface? (Consider the density of water = 1000 kg m⁻³, 1 atm = 1 × 10⁵ Pa and gravitational acceleration g = 10 m/s²)
A
990 m
B
9900 m
C
99 m
D
9000 m
Correct Answer
Option A
Detailed Explanation
The pressure at a depth h in a fluid is given by P = P₀ + ρgh. Here, P₀ is atmospheric pressure, ρ is the density of the fluid, and g is gravitational acceleration. Solving for h gives h = 1000 - 10 = 990 m.
