Class 11 Physics — Chapter 10: Mechanical Properties of Fluids
66 practice questions · 22 Easy · 22 Medium · 22 Hard
Practise Class 11 Physics Chapter 10, "Mechanical Properties of Fluids", with 66 NCERT-aligned multiple-choice questions. The set is split into 22 Easy, 22 Medium and 22 Hard questions, so you can warm up on the fundamentals and then push into the exam-level problems that separate top scorers in CBSE Board exams, JEE Main, JEE Advanced and NEET UG.
"Mechanical Properties of Fluids" is one of the chapters where numerical problem-solving, derivations and conceptual application really pays off. Each MCQ on this chapter is timed and uses exam-grade marking (+2 correct, −1 wrong, 0 skipped), training the same accuracy-under-pressure that real papers demand. Every question carries a short explanation, so a wrong answer becomes a quick lesson rather than a dead end — the fastest way to close gaps before a test.
Use this chapter as targeted revision: attempt the Easy set first to confirm your basics on Mechanical Properties of Fluids, then move to Medium and Hard to test application and problem-solving. Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 11 Physics mastery score. A few sample questions are shown below; sign in free to practise all 66.
Key concepts: Mechanical Properties of Fluids (Class 11 Physics)
This chapter covers fluid statics and dynamics — pressure, Pascal's and Archimedes' principles, Bernoulli's theorem, viscosity and surface tension.
- Pressure in fluids
- Pressure increases with depth (P = ρgh); Pascal's law: pressure applied to an enclosed fluid is transmitted equally.
- Buoyancy
- Archimedes' principle: an immersed body experiences an upthrust equal to the weight of fluid displaced.
- Bernoulli's principle
- For streamline flow, P + ½ρv² + ρgh is constant — faster flow means lower pressure.
- Viscosity
- Internal friction in a fluid; Stokes' law gives the viscous drag on a sphere and the terminal velocity.
- Surface tension
- The contracting tendency of a liquid surface; explains drops, capillary rise and excess pressure inside bubbles.
Key formulas — Mechanical Properties of Fluids
💡 Exam tips for Mechanical Properties of Fluids
- Bernoulli's principle (faster flow → lower pressure) explains lift on a wing and the spray pump.
- At terminal velocity the net force is zero (weight = buoyancy + viscous drag).
Sample questions
SI unit of pressure:
Pa = N/m².
Bernoulli's equation expresses conservation of:
P + ½ρv² + ρgh = constant.
Viscosity is a measure of:
η resists relative motion between fluid layers.
