Exercise Question 9.7 | Mechanical Properties of Fluids | Class 11 Physics | NCERT | Sadhana Classes

In this video, we solve Exercise Question 9.7 from Class 11 Physics chapter Mechanical Properties of Fluids with a clear, simple, and step-by-step explanation based strictly on the NCERT syllabus. This question focuses on important concepts such as viscosity, coefficient of viscosity, terminal velocity, and the application of Stokes’ law in fluid mechanics. Students will learn how resistive force acts on a body moving through a viscous fluid, how terminal velocity is achieved, and how physical quantities like radius, density, and viscosity affect the motion of objects in fluids. The full derivation, correct formula usage, and proper substitution are explained to avoid common mistakes made in exams. This solution is extremely useful for Class 11 CBSE and State Board exams, and also forms a strong base for NEET and JEE preparation, where numerical questions from fluid mechanics are frequently asked. The explanation is designed in an exam-oriented manner to help students improve conceptual clarity as well as numerical problem-solving skills.
