NEET Physics Pressure in Fluids MCQ Question
A submarine is at a depth of 1000 m in seawater with a density of 1.03 × 10^3 kg/m^3. Calculate the gauge pressure experienced by the submarine. Assume g = 10 m/s^2.
103 × 10^5 Pa
104 × 10^5 Pa
102 × 10^5 Pa
105 × 10^5 Pa
Correct Answer
Detailed Explanation
The gauge pressure is calculated using the formula P_g = ρgh. Substituting the given values: P_g = 1.03 × 10^3 kg/m^3 × 10 m/s^2 × 1000 m = 103 × 10^5 Pa.
